Duration 5 Days 30 CPD hours This course is intended for This is an intermediate course for people who need to write and maintain Rexx programs in the z/OS system environment. Overview The objectives of this course are as follows:- Write programs using the Rexx language- Use various data parsing techniques- Use built-in Rexx functions- Create user-defined internal and external functions and subroutines- Issue host commands from within Rexx execs- Code programs that read and write data sets- Use instructions and commands that manipulate the data stack- Use Rexx debugging tools- Write error-handling routines This course is designed to teach you the basic skills required to write programs using the REXX language in z/OS. The course covers the TSO extensions to REXX and interaction with other environments such as the MVS console.
