Recommended Duration:  2 Days

Benefits:  APIs stands for Application Programming Interfaces; students who complete this course will be able to design and maintain applications using native TSO commands and the powerful REXX capability of TSO. We also discuss invoking TSO commands and working with REXX variables from programs written in Assembler, PL/I, COBOL, and C.

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

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