Note: this is the OS/2 release in which REXX became part of the base operating system. It had previously been included in the IBM OS/2 Extended Edition 1.2 only.
NUMBER 290-691 DATE 901030 TYPE Programming TITLE IBM OPERATING SYSTEM/2 STANDARD EDITION VERSION 1.3 AND OPERATING SYSTEM/2 PROGRAMMING TOOLS AND INFORMATION VERSION 1.2/1.3 ABSTRACT Operating System/2 (R) (OS/2 (R)) Standard Edition (SE) Version 1.3 fulfills IBM's stated intent to deliver in OS/2 Standard Edition a 2MB OS/2 entry system and to further expand the range of OS/2 capable systems. Operating System/2 Programming Tools and Information Version 1.2/1.3 will assist application developers to fully utilize this new function. IBM Operating System/2 Standard Edition Version 1.3 has been enhanced to provide increased performance in memory-constrained environments, and reduced requirements for system memory and fixed disk space. Also provided are Procedures Language 2/REXX, enhanced font support, improved printer device drivers and usability enhancements.

DESCRIPTION BUSINESS SOLUTIONS In addition to all previously announced function, IBM Operating System/2 Standard Edition Version 1.3 provides increased performance over OS/2 SE 1.2. IBM Operating System/2 Standard Edition Version 1.3 is faster in performing system functions than OS/2 SE 1.2 in memory-constrained environments. (A memory constrained environment is caused when applications overcommit system memory and disk swapping occurs). The minimum system storage required to operate OS/2, including the DOS compatibility mode, has been reduced from 2.5MB to 2.0MB. This reduction will allow many Personal System/2 (R) (PS/2 (R)) systems to utilize the true multitasking of IBM Operating System/2 Standard Edition Version 1.3 without additional storage. NOTE: 2.5MB or greater system memory and a 60MB or greater fixed disk partition are recommended for use with the high performance file system. A new selectable install utility allows IBM Operating System/2 Standard Edition Version 1.3 to install in less fixed disk storage than OS/2 SE 1.2, freeing more space for user programs and data. The smallest install will require approximately 8.0MB of fixed disk space and the full install 11.0MB on a system with at least 4MB of system memory.

GROWTH ENABLEMENT IBM Operating System/2 Standard Edition Version 1.3 includes Adobe Type Manager and will be shipped with IBM's core set of fonts. Adobe Type Manager accepts Adobe Type 1 outline fonts to provide high quality typographic text in a full range of sizes and styles to all IBM Operating System/2 Standard Edition Version 1.2 supported printers and displays, providing "What You See Is What You Get" (WYSIWYG) technology for OS/2 Presentation Manager (TM) (PM) applications. Over 600 different typefaces available in Adobe Type 1 font format can now be used with OS/2. (TM) Trademark of International Business Machines Corporation. The twelve core fonts included with IBM Operating System/2 Standard Edition Version 1.3 are: o Times New Roman (2) o Times New Roman Bold o Times New Roman Italic o Times New Roman Bold Italic o Helvetica (3) o Helvetica Bold o Helvetica Italic o Helvetica Bold Italic o Courier o Courier Bold o Courier Italic o Courier Bold Italic Adobe Type Manager requires no new application programming interfaces and works with existing OS/2 applications that use Presentation Manager outline fonts. IBM Operating System/2 Standard Edition Version 1.3 will support additional vendor font-rendering technologies developed for use with IBM Operating System/2 Standard Edition Version 1.3. IBM Operating System/2 Standard Edition Version 1.3 includes Procedures Language 2/REXX (REXX). REXX is an easy-to-learn language designed to facilitate the writing of clear, structured, interpreted procedures. REXX can provide the data manipulation and procedural logic framework for OS/2 commands and conventional calls to other high-level languages and CMD programs. The REXX interpreter implements both the SAA (TM) level 1 and the SAA level 2 definition of Procedures Language. Because of this, it provides a more portable procedural alternative to OS/2 CMD programming, reducing the programming investment for users who require applications that execute in several SAA environments. REXX helps protect programming investment for users who already developed REXX procedures for other SAA environments. REXX was previously available in OS/2 Extended Edition Version 1.2. REXX also includes a repertoire of arithmetic, string handling, and logic operations that can be interpreted by OS/2. Users may use REXX as a personal computing language without requiring a compiler. The extended repertoire in this interpreter can enhance programmer productivity. In addition, REXX may be used to extend an application by creating macros that have a mix of REXX instructions, application specific instructions, and OS/2 commands. The limit on the number of active Presentation Manager windows has been increased 10 - 20 times over IBM Operating System/2 Standard Edition Version 1.2 in the same environment. IBM Operating System/2 Standard Edition Version 1.3 remains
