NUMBER 293-063 DATE 930209 TYPE Programming TITLE IBM REXX/VSE VERSION 1 RELEASE 1 ABSTRACT REXX/VSE (5686-058) supports both interpreted and compiled EXECs. REXX/VSE enables the powerful Systems Application Architecture (R) (SAA (TM)) REXX language in the VSE Batch environment to do many tasks and VSE operations automation. The easy-to-use REXX language allows programs to be written in a clear and structured manner. Its key characteristics include powerful character string manipulation, automatic data typing, and high-precision arithmetic. Using REXX for automation tasks has the advantages of increased productivity, consistency, simplification and usability over other methods. In addition, since REXX is an SAA language, both REXX programs and knowledge can be ported between systems. REXX/VSE is highly readable and easy to learn and use. It allows the user to build and send commands, and facilitates the handling of arrays. REXX/VSE has a rich set of built-in functions; built-in parsing with many options; and offers dynamic interpretation. It includes condition trapping to save the user from coding many error checking routines. Planned Availability Date: September 17, 1993.

IN BRIEF . . . o VSE/ESA Operation Automation enables direct communication to the operator console and may be used for automation, substitution, and/or parameterization of VSE Job execution. o Support for both interpreted and compiled REXX programs is included in this product. It consists of both a full REXX interpreter and the library for REXX/370. The library allows REXX programs compiled on TSO or CMS to be executed. o JCL streams can be created dynamically via REXX EXECs. o REXX can be used in any partition like other application languages. o SAA compatibility that allows porting of REXX programs and development of common applications between platforms. This increases customer value for all VM/VSE users. o Offers consistent REXX interfaces with the TSO/E implementation that increases portability of MVS subsystems and applications to VSE.
