What about the ASMA90 program? It can be invoked via JCL and process the PARM=. But it can also be LINK'd to or ATTACH[X]'d. In this latter case, The parmlist passed in via GPR1 can have more than one entry. The others are for things like overriding DD names. Many of IBM's utilities (such as IDCAMS) use this facility. I have written a program which invokes IDCAMS and redirects the "SYSIN" and "SYSPRINT" DD statement to a subroutine in my code so that I could send a command to IDCAMS and then get the result back, in order to futher process it.
