This course is a continuation of the fundamentals course TSO/E REXX.

In this advanced course:

• participants learn to use the REXX utilities more efficiently by means of several techniques;
• the different TSO/E and non-TSO/E interfaces for use in REXX procedures are thoroughly examined;
• participants learn to adapt and broaden the REXX environment by means of function packages.

• REXX techniques:
  • Parameter transmission between REXX execs • subroutines and functions
  • Use of the data stack and the buffer mechanism
  • Use of stem variables (arrays)
  • Error treatment and conditions (SIGNAL ON ERROR, HALT, FAILURE, ...)
  • Interactive tracing

  • ISPF dialog manager
  • PDF edit macro's
• REXX in non-TSO/E address spaces (batch, MVS, ...)
• Interfaces to QMF • Db2 • CICS • IMS
• REXX built-in functions
• Definition and use of function packages
• SDSF REXX

Classroom instructions. About 40% of the time is spent on practical exercises.

Delivered as a live, interactive training – available in-person or online, or in a hybrid format. Training can be implemented in English, Dutch, or French.
