Create REXX Variables

User-written functions written in assembler language can create and extract REXX variables using the standard TSO/E REXX IRXEXCOM service. You can get the address of the REXX variable service routine from the EXTE pointed to by the environment block (register 0 on entry to the function). QUEUE is the only supported function.

For more information on the IRXEXCOM service, see the IBM documentation.
