This 2 day course will introduce students to the advanced facilities available for coding REXX execs in a z/OS or OS/390 environment. A series of written and lab exercises will be used to reinforce the classroom education.

Programmers, technical support personnel, and other individuals that need to write REXX execs.

Upon successful completion of this course, the student will learn to:

• Code user-developed REXX subroutines and functions
• Use ISPF services in REXX execs
• Read and write sequential datasets
• Manipulate and access the REXX data stack
• Create REXX based ISPF edit macros
• Execute REXX execs in batch jobs
• Compile and linkedit REXX execs
• Code REXX execs that interact with DB2
• Code REXX execs that issue MVS operator commands

• User-defined Subroutines and Functions
• Using ISPF Services in REXX
• File I/O
• Data Stack Processing
• ISPF Edit Macros
• Advanced REXX Topics
• Supplemental Topics (as time permits)

Basic z/OS REXX Programming, or equivalent experience.
