Allocation Requirements for REXX Environments
Before running SA z/OS you may need to change the maximum number of REXX environments allowable.
The number of REXX environments allowable is defined in the REXX environment table. See z/OS TSO/E Customization for more information.
TSO/E provides a SYS1.SAMPLIB member called IRXTSMPE, which is an SMP/E user modification to change
the maximum number of language processor environments in an address space.
Define the number of allowable REXX environments on the IRXANCHR
macro invocation:
IRXANCHR ENTRYNUM=xxxInstall the user modification by following the instructions in z/OS TSO/E Customization.
