Integrating Company-Wide Computing Resources
Open Desktop is ideal for organizations that have a variety of different systems and networks and want
them to intemperate. Because it is based on acknowledged open system standards, Open Desktop
protects and enhances the current hardware and software resources of these organizations, while
freeing them from dependence on any single hardware or software vendor. As a result, Open Desktop
gives these organizations the flexibility and confidence they require to establish their MIS strategies for
the '90s and beyond.
Government, business, technical, and manufacturing organizations are choosing Open Desktop as their
platform for developing and deploying network-distributed, graphical applications that are critical to
their day-to-day operations. These "mission-critical" applications integrate information from all of their
offices - both local and remote - and make it quickly and easily accessible to other employees around
the world.
Organizations are also using Open Desktop to continue to leverage their investment in 386 and 4 86
systems by employing these industry-standard computers as advanced business workstations. These
systems are serving as executive workstations and advanced decision-support systems, as well as client
workstations in distributed computing environments.
Organizations are also using Open Desktop on 3 86/486 systems as standard technical workstations.
Open Desktop supports the new generation of technical applications based on the X Window System ™ ,
and these industry-standard workstations can be networked with existing proprietary workstations. As a
result, Open Desktop provides a cost-effective solution for extending the number of technical stations
available to technical workgroups.

system administrators with additional information on all of Open Desktop 's capabilities. Also
separately available are SCO MPX™, the performance extension for multiple processor SCO systems;
SCO 's packaged-product version of Microsoftt LAN Manager for UNIX Systems; and SCO 's C++
development system.
The base, single-user Open Desktop system integrates five powerful system services- UNIX
System V, graphical user interface, database, networking, and MS-DOS-UNIX System integration.
Open Desktop 's UNIX System engine is the 32-bit, multiuser, multitasking SCO UNIX System V/386
Release 3.2 Version 2.0- the standard for UNIX Systems on 3 8 6 and 486 systems.
Open Desktop's graphical user interface (GUI) is the industry-standard OSF/Motif™, which is based on
the X Window System and provides appearance and behavior similar to that of Microsoft Windows™
and Presentation Manager. The GUI also includes a convenient Desktop Manager, which provides users
with an easy-to-use icon- , menu- and mouse-driven system interface.
Because Open Desktop includes TCP/IP and LAN Manager networking support, it comes ready to
connect to MS-DOS, OS/2•, XENIX, and UNIX Systems. Open Desktop NFS•• services provide
distributed file system support.
Open Desktop 's database management services, based on the structured query language (SQL), can
operate locally or over networks , enabling access to distributed mainframe and minicomputer database
systems, as well as access to other Open Desktop database servers in a distributed information
environment.
Finally, Open Desktop is directly compatible with thousands of existing MS-DOS, XENIX, and UNIX
System applications currently available.
Open Desktop fully integrates the following technologies into a single, efficient, eas y-to-use system:

Open Desktop takes full advantage of today 's 386 and 486 microcomputers by bringing a graphical
user interface to the UNIX System environment that is consistent with today 's most popular and
easy-to-use interfaces. It integrates proven, open system technologies into a complete, network-ready
solution. And, it brings the capabilities formerly associated with much larger, proprietary platforms to
industry-standard systems at substantially lower costs.
These new computers pack the power of minicomputers an(! proprietary workstations, but without the
problems of limited configurability and costly upgrades, m aintenance, and support. The new,
high-perform ance, industry-standard computers are creating a market for feature-rich, network-ready,
shrink-wrapped graphical applications available through standard distribution channels, including
major distributors , resellers, VARs, systems integrators, and OEMs.

SCO Open Desktop
The Co�plete Graphical Operating System
An Open System for Freedom of Choice
Open Desktop integrates proven, open system technologies from the The S anta Cruz Operation, Inc.
and other industry leaders, including AT&T, Lachman Associates, Inc., Locus Computing Corporation,
Microsoft Corporation, Open Software Foundation, Inc. (OSF) , and the Ingres division of ASK
Computer Systems, Inc. All Open Desktop system resources are designed to meet established U . S .
government, international, and industry standards, including FIPS POSIX™ , the X/Open.., Common
Applications Environment (CAE), ANSI, C2 Trusted Security, and the Intel 386 Architecture Binary
Compatibility Specification Edition 2 (iBCS-2).
Open system computing took a m ajor step forward in August, 1 990, when SCO, AT&T 's UNI X System
Laboratories, Inc. (USL), and Intel Corporation agreed to define iBCS-2, a common binary
compatibility specification for UNIX Operating Systems based on 386 and 486 PCs. The iB CS-2
specification ensures users and developers that their applications will run out-of-the-box under Open
Desktop and SCO UNIX System V operating systems, as well as under the next revision of AT &T 's
UNIX System V/3 8 6 Release 4 (SVR4). Prior to the signing of the iBCS-2 accord, The Open Software
Foundation (OSF) had already m ade a commitment to provide compatibility with Open Desktop, SCO
UNIX System V/3 86, and SCO XENIX 386 in the OSF/1™ operating system .
The iB CS-2 accord brings a single standard- in a similar m anner to MS-DOS- to the open system
marketplace. Developers can use Open Desktop and other SCO operating systems to create a single
version of their UNIX System applications that will run on OSF/1 , SCO UNIX Systems, SVR4, and
other operating systems compliant with iB CS-2. Open Desktop 's standard Application Programming
Interfaces (APis) allow application developers to access its graphical user interface, networking,
database management, and MS-DOS-UNIX System integration serv ices- without the need to purchase
and integrate individual components.
In April of 1 99 1 , SCO joined with other leading software and hardware vendors, including Compaq,
Digitial Equipment Corporation, Microsoft, MIPS Computers, and 1 6 other hardware vendors, to
establish the Advanced Computing Environment (ACE) initiative. ACE will enable organizations to
utilize industry-standard systems for a variety of platforms, from the desktop to the d ata center. B y
defining the standard components o f an advanced computing environment, including both hardware
and operating syst{lmS, ACE will-ensure the highest level of interoperablility, scalability, and portability
among both Intel (x 86) and ARC (Advanced RISC Computing) systems.
The ACE initiative specifies Open Desktop as the unified UNIX System for a new family of
industry-standard computers based on the ARC specification. The ARC specification defines an open
RISC computing architecture for MIPS RISC microprocessor-based systems. Available today on
x86-based platforms , Open Desktop is planned for release on ARC platforms as hardware vendors
bring ARC-compliant systems to m arket. Because Open Desktop platforms provide source-level
compatibility between environments, Open Desktop solutions can be developed today on x 86-based
systems and quickly moved to new ARC systems as they become available. This m akes Open Desktop
the ideal choice for implementing advanced computing environments today, as well as in the future.

Open Desktop Technology
•
Open Desktop provides end users and developers with proven, open system technologies in an
integrated product- all from a single source. Each of Open Desktop's system services- UNIX System,
GUI, networking, database, and MS-DOS- is described in detail below.
UNIX System Services
•
Open Desktop's UNIX System services include a 2-user license for SCO UNIX System V /3 8 6 Release
3.2;* the Open Desktop Server Upgrade provides a multiuser license for SCO UNIX System V. SCO
UNIX System V enables Open Desktop to take full advantage of the 32-bit capabilities of 3 8 6 and 486
machines, and to benefit from the power and performance formerly associated with proprietary
workstations, departmental servers, and minicomputers.
With SCO UNIX System V as its engine, Open Desktop provides significantly more power and
capabilities than other 386-and 486-based operating systems by including:
• True, 32-bit processing capabilities-to take advantage of more powerful programs
• Demand-paged, virtual-memory management- the ability to run programs larger than installed
RAM through automatic paging to the hard disk
• True multitasking- allows multiple programs to run simultaneously on a single system within
different windows
• Highly efficient file-system management-provides high-performance file management to
increase performance when accessing large amounts of information
• Configurable system security- allows users and system administrators to protect information and
system access from unauthorized users
• Based on industry standards- provides system with built-in interoperability and applications
compatibility, portability, and scalability to other systems
• Multiuser upgradability- allows true multiuser capabilities with complete file-locking,
password-protection, and flexible configuration options
SCO UNIX System V provides UNIX System features, such as a menu-based set-up and administration
shell, plus the Acer Fast File System (AFS) and AT&T File System Switch (FSS). SCO's device drivers
support dozens of standard peripherals, including SCSI devices. In addition, SCO's modular, extensible
console driver supports standard and non-standard consoles. SCO UNIX System V is designed to
support all major international standards including:
• Federal Information Processing Standard (FIPS) 151-1 (IEEE POSIX 1003.1 with all extensions)
• ANSI X3J11 C-Language Standard
• Department of Defense National Computer Security Center (NCSC) C2 Trusted Computing Base

Graphical User Interface (GUI)* Services
Open Desktop's GUI services combine industry-standard technologies into an open system platform
that can be used as a graphical environment for personal productivity or as a network-distributed
graphical solution. In all applications, these GUI services provide the appearance and behavior of
Microsoft Windows and Presentation Manager, providing consistent operation on both MS-DOS-based
and Open Desktop-based platforms.
Because Open Desktop supports the industry-standard OSF/Motif GUI, applications running across
divergent platforms appear and behave the same. This consistency of appearance and behavior
preserves users' investments in hardware, software, and training.
Using a mouse or keystrokes, the user simply "points and clicks" on icons, pull-down menus, and
control buttons to operate the system and applications. Full multitasking functionality- either graphical
or character-based - enables the user to view and run multiple applications in separate windows at the
same time. And because of the networked resource-server capabilities of the X Window System,
programs can run locally or on another machine located elsewhere on the network.
Open Desktop's GUI services include a runtime GUI consisting of the following industry-standard
components:
• X Window System Server
• OSF/Motif Window Manager
• X.desktop Desktop Manager
The X Window System Server is the industry standard for network-distributed, graphical windowing
systems. The X Window System Server provides services that enable Xll- and OSF/Motif-based client
applications to run locally or remotely via the network. That is, any Xll-based or OSF/Motif-based
client or application can operate on Open Desktop. The X Window System Server manages the clients
by providing services for display, keyboard, and mouse operation. It also supports Hercules, EGA,
VGA, and Super VGA displays.
With the OSF/Motif Window Manager, you can display running programs as icons, and customize the
desktop and Window Manager menus. The OSF/Motif Window Manager complements the X Window
System and supports the Microsoft Windows and Presentation Manager behavior and 3-D appearance.
Each OSF/Motif window has several buttons which you can use to to move, resize, overlap, and "leaf
through" multiple windows.
The Desktop Manager (X.desktop) completes Open Desktop's GUI services. When working with Open
Desktop, you use the OSF/Motif Window Manager to operate the window system, and you use the
Desktop Manager (built from the OSF/Motif toolkit) to operate graphical applications and the UNIX
System. The Desktop Manager eliminates any need for the user to learn and employ unfamiliar UNIX
System commands. Instead, you simply "drag" icons across the screen and onto a "desktop action"
icon. For example, to print a file, you drag a file icon over to a print icon. To delete a file, you drag a
file icon· over the "trash can" icon.
•
A graphical user interface
(GUI) can be defined as the appearance and behavior of an application and the associated graphics
applications programming inte rlace
(API).
Open Desktop's GUI consists of a runtime graphics environment (X 1 1 Window
Server, OSF/Motif Window Manager, and X 1 1- and OSF/Molif-based clients comprising the Desktop Manager) and an API
(User Interlace Toolkit: Xlib, Xt, OSF/Motif; Style Guide; User-Interlace Language).
17
SCO Open Desktop
The Desktop Manager is both extensible and flexible. It provides a powerful "rules" language that
defines the appearance and behavior of objects. The Desktop Manager is compatible and complies with:
Xt Intrinsics
• ICCCM (Inter-client Communications Conventions Manual)
• X/O pen
• POSIX
•
Open Desktop's GUI services also include scoterm, a utility that provides full-color SCO console (and
ANSI console) support within windows. This utility enables the user to run virtually all existing
XENIX and UNIX System applications in windows.

Networking Services
Open Desktop is designed to provide the user with instant access to data, applications , and resources
throughout an organization - in the department next door or the branch office thousand s of miles away.
Open Desktop 's networking services, which include TCP/IP, NFS , and LAN Manager Client, can
interface with Ethernet and Token Ring network architectures.
TCP/IP Networking
TCP/IP is an underlying layer of software that connects machines into a local-area network (LAN), and
connects LANs across wide-area networks (WANs) to enterprise-wide networks . Transmission Control
Protocol (TCP) and Internet Protocol (IP) are standard communications protocols. TCP/IP is the
foundation of many network-based programs. Application programs and system software rely on
TCP/IP to send and receive information to and from remote machines.
TCP/IP includes the rlogin, telnet, and ftp utilities, which allow you to log into , and transfer files
from , remote m achines on a network. With TCP/IP, you can connect machines locally, using cables, or
remotely via modems and telephone lines.
TCP/IP networking ensures that users can share data and resources on other systems. TCP/IP provides
high-performance Ethernet network connections to a wide variety of computers . Even on networks
composed of dissimilar hardware and operating systems, users can quickly and easily log into remote
machines and access peripherals or share data. TCP/IP protocols are used by graphical windowing
products, such as the X Window System; distributed file-system products, such as NFS; distributed
database products, such as INGRES; and by many business and scientific applications .
Open Desktop's TCP/IP implementation supports popular 3Com and Western Digital LAN cards and
includes Serial Line Internet Protocol (SLIP) drivers to support asynchronous gateways or bridges .
SLIP asynchronous connections can be implemented between local machines and across WANs.
TCP/IP also supports distributed applications through the standard AT&T Transport Layer Interface
(TLI) interprocess communications mechanism. TCP/IP uses a Streams-based architecture fo r high
performance and flexible configuration control. Included in the TCP/IP Development System is a BSD
4.3-compatible socket library, which allows developers to adapt existing (o r create new)
BSD-compatible distributed applications that take advantage of interprocess communication (IPC) both
locally and across networks .
Open Desktop contains a complete protocol suite, featuring :
•
Standard ARPA utilities: telnet, ftp
•
Berkeley (BSD 4.3) R-utilities: rlogin, rep, rcmd, rslh., rwho, ruptime, finger
•
B IND name service (client/server support)
•

SCO Open Desktop
Network File System
Network File System (NFS), developed by Sun Microsystems, is the de facto standard for distributed
file systems in workstation environments. Using NFS within a network composed of machines running
several different operating systems, users can access remote files and applications directly - just as if
they resided on the user's own machine.
NFS creates a truly distributed file system by mounting remote file systems. NFS reduces the need for
time-consuming remote logins and eliminates the confusion and wasted disk space that results from
having multiple copies of a file on several machines.
NFS also provides the foundation for developing and executing applications that take advantage of
file-sharing connections across TCP/IP LANs to computers supporting compatible networlc file
systems. Open Desktop's NFS features Sun-compatible Remote Procedure Calls (RPC) and eXternal
Data Representation (XDR) libraries for the development of distributed applications. RPC allows
remote procedures to be invoked as if they were local subroutines. It allows processes running on one
machine to be accessed across a network, and it relieves the applications programmer from
involvement with the details of the underlying networking implementation. XDR provides a simple
system- and machine-independent method of specifying data and protocols transmitted between
heterogenous systems.
PC-NFS S erver
PC users with PC-NFS for MS-DOS can access remote files on a network while running applications
under MS-DOS. With Open Desktop's PC-NFS server capabilities (included in the Open Desktop
Server Upgrade), PC users can access Open Desktop file systems directly and transparently. An Open
Desktop file system can appear to PC users as a separate, local disk drive, while Open Desktop
resources, such as printers and modems, can also appear as local resources. And because Open
Desktop's file system and peripherals can be accessed by more than one user on the network at a time,
Open Desktop makes an ideal platform for serving multiple PCs in a shared-resource environment.
• Transparent file access
• File transfers
• Remote system access
• File-system commands
PC-Based Local -Area Networks (LANs)
Open Desktop's LAN Manager client service enables users to access files, applications, and peripherals
on OS/2, MS-DOS, XENIX, and UNIX System servers equipped with appropriate server software. The
LAN Manager client service is based on the SMB (Server Message Block) protocol, and is compatible
with a wide variety of SMB-based PC networks including Microsoft's MS-DOS and OS/2 LAN
Manager products, IBM LAN Server and PC Local-Area Network Program, 3Com's 3+0PEN, and
SCO XENIX-NET. SMB NetBIOS-based protocols are a de facto standard in MS-DOS networking
environments, and have been submitted for inclusion in the X/Open standard.
20
SCO Open Desktop
Open Desktop's LAN Manager Client Services enable Open Desktop users to :
•
Access files on MS-DOS , OS/2 , XENIX, and UNIX Systems
•
Access network resources using server-based validation
Use remote pathnames to transparently access files on a remote m achine
•
Access a LAN Manager server
•
Display network-status information
•
Print remotely, using MS-DOS, OS/2 , XENIX, and UNIX System printer resources
•
Open Desktop's PC-Interface Server, included in the Open Desktop Server Upgrade package, connects
an Open Desktop Server with MS-DOS-based personal computers running the MS-DOS version of
PC-Interface, either via RS-232 serial lines or in a LAN. From a personal computer runni ng separately
available PC-Interface client software - using either MS-DOS or UNIX System commands - the
MS- DOS user can access all Open Desktop Server resources, including files and printers, regardless of
their location on the network.
PC-Interface also includes a standard terminal emulator enabling remote MS-DOS systems to access
and run UNIX System (character-based) applications located on an Open Desktop server. PC-Interface
also includes the built-in National Language Support (NLS) for use in international installations. User
messages are readily translatable into local languages, and include extensive support for converting
files between different international standards.
In addition, PC-Interface includes a comprehensive set of features that effectively network MS-DOS
and UNIX System operating environments . Some of these features include:
Based on Industry Standards

MS-DOS Services
Open Desktop's MS-DOS services provide complete MS-DOS to UNIX System integration
capabilities. With these MS-DOS services, multiple MS-DOS-based applications can run in windows
simultaneously, along with multiple XENIX and UNIX System applications. Users can select and run
many of the thousands of off-the-shelf MS-DOS applications directly - without special commands,
data conversions , or application filters. Open Desktop 's MS-DOS services create a "virtual 8086
personal computer" running a licensed copy of MS-DOS Version 3.3 under the UNIX System. Both
character-based and graphical MS-DOS applications are supported. Open Desktop 's MS-DOS services
support graphical MS-DOS applications in CGA graphics mode within an X window, and support the
higher-resolution EGA and VGA graphics in full-screen mode. Microsoft Windows 3 .0 and Windows
3.0 applications are also supported, in real mode, under Open Desktop's MS-DOS services.
Open Desktop supports many popular, standard PC peripherals, along with additional hardware,
through the "Direct Device Attachment. " With the Direct Device Attachment, MS-DOS-based
programs can access specialized devices directly via an MS-DOS device driver, eliminating the need to
have a UNIX System device driver for that specific device (on ISA and EISA machines only).
With its MS-DOS services, Open Desktop preserves the user 's existing investments while enhancing
productivity. Open Desktop 's UNIX System capabilities - such as its fully paged, virtual-memory,
multitasking capabilities - are available to MS-DOS programs and users. Open Desktop fully integrates
the MS-DOS file system within the UNIX System so that a separate partition is not required to run
MS-DOS-based programs. In addition, the full power and benefits of the UNIX System are made
available to MS-DOS users , such as the efficient, high-performance UNIX System file system,
read-write-execute file-permission modes , password security, and much more.
Open Desktop's MS-DOS services support an expanded memory specification (EMS LIM 3 .2) which
allows MS-DOS applications to use up to 8 additional Mbytes of memory above the standard 640
Kbytes.
With Open Desktop, users can:
o
Execute familiar MS-DOS commands and applications in an Open Desktop window
o
Run multiple MS-DOS and UNIX System applications concurrently
•
Combine MS-DOS and UNIX System processes in a single application
•
Integrate MS-DOS and UNIX System peripherals without developing additional drivers
Users can activ ate Open Desktop 's MS-DOS services in several ways : by double-clicking the mouse
button on the MS-DOS icon in the desktop window, by typing the name of an executable MS-DOS file
while in a UNIX System window, by double-clicking on an MS-DOS-based icon, or by running an
MS-DOS (command line) in a window.

Database Services
In most large organizations, critical information-management tasks are handled by a combination of
mainframes, minicomputers, PCs, and workstations. These systems are connected via networks to get
information into the hands of key decision makers. In these heterogeneous environments, it can be a
major challenge to integrate corporate data and make it accessible to users at their desktops. In addition
to m aintaining high-performance processing for mission-critical applications , organizations must
deliver information across a wide variety of hardware, software, and local-area networks (LANs).
Open Desktop's database services help you make better strategic decisions by m anaging information
more effectively at the desktop and server levels.
The evolution of the workstation and its emergence as a key technology for distributed processing has
increased the demand for sophisticated database services that are tightly integrated with the operating
system . To access local and remote information, users need the workstation to provide a rich set of
RDBMS capabilities. To serve this need , Open Desktop includes a complete, robust set of
industry-standard RDBMS tools.
Open Desktop 's database serv ices incorporate a sophisticated relational database m anagement system
based on the industry-standard structured query language (SQL) , as well as SCO 's implementation of
the Indexed Sequential Access Method (ISAM). Although Open Desktop's relational database
management system is based on INGRES Version 6.2 technology, other RDBMSs can be used.
Database m anagement systems compatible with Open Desktop include products from Informix, Oracle,
and Sybase. You can use Open Desktop 's built-in SQL database or the database m anagement system of
your choice to provide an excellent platform for personal inform ation-management systems, servers ,
and distributed systems that access central databases across corporate networks.
Open Desktop 's SQL database can operate locally or over an Ethernet Token Ring network to bring the
power and functionality of mainframe database services to 3 8 6 and 486 systems. Open Desktop
includes consistent, interactive query and reporting facilities (Query-B y-Forms and Report-B y-Forms),
and networked SQL functionality, which allows networked database applications to operate
transparently in heterogeneous environments.
Open Desktop provides a versatile platform for client-server database implementations , using the
industry-standard TCP/IP communications protocol. Multiple end-user m achines can transparently
share alphanumeric and graphical data located in a central database server. Many users can store and
retrieve d ata on the shared database server while maintaining a high level of data integrity. Open
Desktop applications can access other host databases such as DB2 by using INGRES G ateways.
With Open Desktop, you can run more than one database function at one time by using multiple
windows. You can easily "copy and paste" information between windows, or within a single window.
With Open Desktop, you can :
•
View or update data from one or more tables
•
Display and print reports, which are specially formatted data displays
•
Use Forms, an online version of a paper form , to query the database or add data to the database
•
Use S QL to create tables, add data, and query for data

query-language statements and results in a file.
Open Desktop's database services also include ISAM, SCO 's implementation of X/Open's Indexed
Sequential Access Method (ISAM) interface for managing indexed files. You can use ISAM 's library of
C-language functions to create and manipulate indexed files . Open Desktop's ISAM has been
fine-tuned to provide the highest-perfonnance data-management applications. ISAM is call-compatible
with other X/Open-compatible ISAM libraries such as Informix 's C-ISAM. ISAM fully supports
multiuser applications via file- and record-locking procedures.
Database Extensions
The Ingres division of ASK Computer Systems, Inc. offers a full suite of value-added products for
Open Desktop's database services. These products allow for full development and deployment of
applications within the Open Desktop environment.
Windows 4GL™ gives developers the power to quickly produce database (\9plications which can access
the capabilities of the Open Desktop GUI services, while avoiding the usual complexities of
workstation programming. Applications are portable across workstation platfonns from other vendors.
Windows 4GL gives you the ease of use of both a GUI and a powerful 4GL for building
mission-critical applications far more rapidly and efficiently than if you were using C and a windowing
tookit.
Applications-by-Fonns (ABF) is a character-based 4GL development system for creating, examining,
and modifying any fonns-generated application. ABF provides a complete menu-driven workbench and
4GL for building applications .
With INGRES Gateways you can easily integrate existing files and databases into a comprehensive
information-management system. Using a gateway, your applications can process existing infonnation
as if it were actually in an Open Desktop or lNG RES database. Applications perfonn S QL operations
on files stored in these non-Open Desktop databases or non-INGRES databases as if they were Open
Desktop databases.

Open Desktop Development System
•
The Open Desktop Development System is a complete application development environment. When
developing graphical applications for engineers and scientists, advanced applications for business
professionals, or mission-critical solutions for corpQrations and government agencies , Open Desktop is
the right choice.
Standard A Pis
A complete set of industry-standard system services makes Open Desktop the perfect platform for
developing the next generation of advanced graphical applications. Developers no longer need to
purchase and install separate components or include these facilities in application programs. Open
Desktop includes standard Application Programming Interfaces (APis) and tools for each of Open
Desktop 's system services.
Open Desktop conforms with all major international standards, including the X/Open Common
Applications Environment (CAE) and the Federal Information Processing Standard (FIPS) 1 5 1 - 1
(IEEE POSIX 1 003 . 1 with all FIPS extensions). As a result, Open Desktop applications are easily
portable to other operating environments, scalable across the range of corporate systems, and
interoperable with other systems over heterogeneous networks. Full internationalization libraries mean
that applications can easily be developed for worldwide markets .

SCO UNIX System V/3 8 6 Release 3.2 conforms with the Intel 3 8 6 Architecture Binary Compatibility
Specification Edition 2 (iB CS-2) for binary compatibility across 386 and 4 8 6 architectures . And you
can use Open Desktop as a cost-effective development platform for applications that are readily
scalable to larger systems.
Many of Open Desktop 's programming tools are provided by the SCO UNIX System V/3 8 6 Release
3.2 Development System , ensuring a development environment consistent with other minicomputer
and workstation-based UNIX Systems. As a result, you and your programming staff will already be
familiar with many of Open Desktop 's development tools. Also provided are online manual pages for
quick and easy reference as well as a complete set of developer's documentation.
28
SCO Open Desktop
Versatile Compilers and Debu ggers
The development system includes advanced software-engineering tools - the ANSI-compatible,
optimizing Microsoft C compiler, the AT&T C compiler which provides source compatibility with
many older programs, and the standard UNIX System Source Code Control System . The powerful
Microsoft Code View source debugger allows the application developer to visually step through
program execution, set breakpoints, and interactively view program output and registers.
X Window S ystem and O SF/Motif Development Tools
The X Window System is a distributed , transparently networked, device-independent, multitasking
windowing and graphics system . It enables the user to display multiple applications in windows on the
same screen, and it lets one application use multiple windows.
The X Window System achieves device independence by using the client-server model. The client is an
application program , generally linked with the X library (Xlib), that requests the server to draw
windows, text, and other objects. The server program runs on each workstation, drawing the required
objects on the display.
Each workstation has its own X-display server, which contains the hardware-dependent drivers for that
workstation. The X server controls the screen, keyboard, and a pointing device. The application
developer links the client program with Xlib, a library of graphics and windowing functions that
translates the graphics operations into the X communications protocol for display by the server.
The client and server can reside on the same machine, or they can be separated across a network. The
X Window System 's open architecture enables the user to transparently operate applications residing
on any host computer on a TCP/IP network.
The X Window System will intemperate with X Window System client applications and other display
servers running on platforms from Sun, DEC, HP, IBM, MIPS , AT&T, Siemens , Sony, NEC, Olivetti ,
Tandy, and many other hardware vendors.
o User Interface Language (UIL) Compiler - a compiler
which allows the applications progranuner to build the
user interface separately from the application engine by
specifying the widget hierarachy and call backs
o
Motif widgets , gadgets, and convenience routines scroll bars, dialog boxes, push buttons, pull-down
menus, etc.
o X Toolkit (Xt) Intrinsics - routines for creating new
widgets and routines, which provide event handling,
geometry management, and displ ay presentations
characteristics
o X Library (Xlib) - low-level graphics routines for
drawing arcs and lines
Th e Open Desktop Developm e nt Syste m prov id es the deve loper with the OS F/Motif and
X W i ndow System too ls
to create bit- m apped c l i ent applications and g raph ical user i nt e rfaces.
29
SCO Open Desktop
Open Desktop's industry-standard X Window System and OSF/Motif development tools enable the
developer to build state-of-the-art, X Window System-based client applications. These tools include
OSF/Motif; the X Toolkit (Xt) Intrinsics; the X Library; over 40 pre-built widgets such as scroll bars,
push buttons, and pull-down menus; and the User Interface Language (UIL) compiler, which enables
the developer to create new widgets and perform two-dimensional drawing.
The OSF/Motif Style Guide enables the developer to produce a GUI consistent with the appearance and
behavior of Microsoft Windows and Microsoft Presentation Manager. As a result, Open Desktop
applications can offer the same familiar interface available with MS-DOS and O S/2 applications.
The X Window System and OSF/Motif graphical user interface are being ported to major platforms
from 386 and 486 PCs to Cray supercomputers. Because the Open Desktop Application Programming
Interfaces conform to these industry standards, source code developed for other platforms will be
readily portable to Open Desktop.
Cross -Development Tools
Open Desktop can be used as a development platform for other operating systems. It includes
cross-development tools for generating MS-DOS, XENIX, and OS/2 object files, which can then be
executed directly in those environments.
M S -DOS -UNIX System Integration
The PCILIB Application Programming Interface gives you a powerful method for combining MS-DOS
and UNIX System functions in a single program.
Database D evelopment
For developing databases, Open Desktop includes an embedded S QL (ESQL) preprocessor for C
programs. This preprocessor provides an efficient means of integrating S QL statements directly in C
source code. The result is a third-generation language application which can automatically m anipulate
a remote or local database. Other preprocessors , for embedding S QL in FORTRAN and COB OL-based
programs, are av ailable from the Ingres division of ASK Computer Systems, Inc.
Open Desktop's database networking architecture is based on the Global Communications Architecture
(GCA) . GCA documents methods for both interprocess and distributed client-to-server and
server-to-server communications. GCA is published and non-proprietary. It is based on the
industry-standard RDA (ANSI 's Remote Data Access) protocol as supported by the ISO 's
(International Standards Organization) OSI (Open Systems Interconnection) model.
GCA provides the foundation for universal, transparent, and open information sharing among an
increasingly wide v ariety of data sources, computer platforms, and network administration and name
services, and an inter-system communications server.
Open Desktop's ISAM implementation has been fine-tuned to provide the highest performance for
embedded data-management applications . X/Open-compatible ISAM libraries provide C-language
functions for creating, accessing, and manipulating indexed file systems used in application programs .
