Control Language Programming Workshop for IBM i [TDS_OL20G]

OVERVIEW

Hands-on course for iSeries students who intend to write Control Language programs to simplify server management and make effective use of system resources.

Virtual Learning

This interactive training can be taken from any location, your office or home and is delivered by a trainer. This training does not have any delegates in the class with the instructor, since all delegates are virtually connected. Virtual delegates do not travel to this course, Global Knowledge will send you all the information needed before the start of the course and you can test the logins.
