TSO/E REXX

During this course:

  • participants learn the practical of the basic principles of the REXX procedural language in the TSO/E environment;
  • they learn to use REXX as programming language and as supporting procedural language with the interaction with TSO and the manipulation of datasets;
  • the REXX test and debugging facilities are explained;
  • the built-in functions of REXX are treated practically.

This course is a good preparation for the course ISPF dialog manager.

Reviews

Goed. Trainer is helder. Het gedeelte van CICS was conceptueel gezien helder alleen erg veel om te bevatten.

Bien adapté aux besoins des débutants. Mais aurait pû etre plus poussé (je suivrai probablement le cours 'advanced')

Il faudrait une journée supplémentaire afin de progresser pluslentement dans le niveau des exercices.
