TSO/E REXX advanced course
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.
No public sessions are currently scheduled. We will be pleased to set up an on-site course or to schedule an extra public session (in case of a sufficient number of candidates). Interested? Please contact ABIS.
