Just a QND to see if this would work for you. It will need some adjustment for
STC, but it might be doable. Enjoy

Subject: Re: Limit to length of PARM= on a START command?
I want to be able to dynamically change the parameters.
Changed the PROC to PARM='&P1&P2&P3' (default to null)
Then I cam specify P1, P2 and P3 on the START command and multiple JCL
statements are generated.
