Advanced TSO REXX Programming

Course Number: 681-TF
Recommended Duration: 2 days

Intended Audience
Applications and systems programmers who need to know how to use the facilities of TSO and REXX from programs written in Assembler, COBOL, or PL/I.

Objectives
Students who complete this course will be able to design and maintain applications using native TSO commands and the powerful REXX capability of TSO. The techniques taught in this class might be helpful in writing mainframe-based server applications.

Prerequisites
At the very least, students entering this course should have experience in using REXX in the TSO environment and in writing programs in one of these languages: Assembler, COBOL, or PL/I.

Topics

Passing arguments to and receiving parameters in compiled programs running in batch and native TSO
Issuing TSO commands from compiled programs (IKJEFTSR service)
Calling programs from an Exec
Accessing, updating, and creating REXX variables from compiled programs running under TSO (IKJCT441 service)
Working with DB2 data from an Exec
REXX dynamic program linkages (ADDRESS LINK, ATTACH, LINKPGM, ATTACGPGM, LINKMVS, ATTACHMVS)
Accessing, updating, and creating REXX variables from a program running in a non-TSO/E-Integrated address space (IRXEXCOM service)
