Chapter 1 INTRODUCTION MPE XL by Korak Mitra--Commercial Systems Division MPE XL, version A.01.10, is the Production Release of the new Hewlett-Packard advanced commercial operating system. Designed to control the next generation of HP Precision Architecture processors, MPE XL provides source code and object code compatibility with applications designed for the MPE V operating system. Built on the foundation of MPE V, MPE XL extends the boundaries of operating system capabilities through greater performance and capacity, higher availability and reliability, and enhanced ease of use and functionality. LANGUAGES Along with advanced operating system capabilities, MPE XL delivers several new Native Mode and Compatibility Mode compilers. Taking full advantage of the HP Precision Architecture hardware, the Native Mode optimizing compilers include: C/XL, COBOL II/XL, FORTRAN 77/XL, and HP Pascal/XL. Providing complete MPE V object code compatibility, the Compatibility Mode compilers include: SPL/V, RPG/V, HP Business BASIC/V, Transact/V, COBOL II/V, FORTRAN 66/V, FORTRAN 77/V, BASIC/V, and Pascal/V. With this combination of compilers, you can use a HP Precision Architecture processor for both MPE V and MPE XL cross-program development. INFORMATION MANAGEMENT MPE XL also delivers TurboIMAGE/XL, which provides maximum Native Mode performance while maintaining full source code compatibility for your database applications. Also available are all of your familiar program development tools including: KSAM/V, DBChange/V, Inform/V, Query/V, Dictionary/V, Report/V, and VPLUS/V. Additional tools in Native Mode include: TOOLSET/XL, HP Symbolic Debugger, and System Dictionary/XL as well as the new Hewlett-Packard relational database technology, ALLBASE/XL HP SQL. Through this array of information management tools, Hewlett-Packard continues to enhance programmer and end-user productivity. DATA COMMUNICATIONS In data communications, MPE XL delivers the Distributed Terminal Controller, which provides flexible local area network-based workstation connectivity. This industry standard 802.3 LAN connectivity frees you from rewiring terminal-to-system connections when expanding or moving. MPE XL also delivers LAN-based NS/XL services, which include: network file transfer, remote database access, remote file access, and virtual terminal capabilities. For wide-area networking capabilities at this production release, MPE XL supports the use of MPE V processors as data communications servers. By using an MPE V processor on the same LAN as the MPE XL processor, Hewlett-Packard provides X.25, point-to-point modem, point-to-point hardwired, SNA and Bisynch wide-area communications. This option is made financially attractive through aggressive rental programs on MPE V data communications servers. OFFICE AUTOMATION At this production release, MPE XL delivers several office automation products including: TDP/V, SPELL/V, and Advance Link. In addition, MPE XL provides Printer Support Package for the Hewlett-Packard 2680A and 2688A system laser printers, as well as IDS/IFS support. Through these host-based and through other pc-based office automation products, you can continue to move the benefits of automation closer to the end-users. ADDITIONAL DOCUMENTATION As part of this MPE XL system production release, you will receive a number of manuals addressing migration, system management, data communications, and other issues. Built on the base MPE V manual set, these MPE XL manuals have been expanded and enhanced for maximum effectiveness. To help you selectively focus on the appropriate manuals to read first, Hewlett-Packard provides a road map into the manual set. See the Documentation and Terminology Guide (P/N 5958-9511) for details. NEW SECTION TO THE COMMUNICATOR The Communicator now contains a new section with more technical detail. For those times when more in-depth information is needed by your programming staff, but is not necessarily relevant to the general reader, the new TECHNICAL ARTICLES section was created. When detailed technical information is available on a product, an article will appear in the new TECHNICAL ARTICLES section.
