Non-TSO/E address spaces

TSO/E provides two programming routines that you can use to run REXX execs, IRXJCL and IRXEXEC.

You can execute a REXX exec in MVS™ batch by specifying IRXJCL as the program (PGM=) on the JCL EXEC statement.

You can call either IRXJCL or IRXEXEC from a program to execute a REXX exec. You can use the IRXJCL and IRXEXEC routines in any address space. describes IRXEXEC and IRXJCL.
