Our Power BI Training Course is especially popular.  Gain new skills, useful tips, and validate your expertise with an industry-leading organisation, all tailored to your schedule and learning preferences.



This REXX training course provides instruction on the use of the Restructured EXtended eXecutor (REXX) language for TSO users who wish to create and use programs written in REXX. The course assumes that delegates have no previous knowledge of REXX. Client feedback shows that delegates on our courses will best engage when they can relate course topics to their own day-to-day practices and requirements. Where possible, we  run this course as a consultative, workshop-style event, in which discussion of relevant topics takes place in relation to the delegates' own applications and scenarios.
