John No need for it to be a single step STC - in fact during QA and testing it is quite common for me to front-end my server program STC JCL with a one or more "primer" steps.
The PPT properties are assigned to the jobstep program. BTW - I make extensive use of MVCDK and MVCSK to pass data between caller and server - they are just hidden inside product macros.

The only way that I can think of would be some sort of serialization to allow the field to be moved, with MVCSK to a key 8 area, update it, then MVCDK back. But that is likely way too much overhead. Doing a couple of SPKA instructions to change to key 2, update, change back to key 8 would likely be simpler. Or, even simplier, just run your server in key 2, exactly as you said to begin with. I guess you use the PPT to assign key 2 to your server's program and running it as a single step STC. > > Rob Scott > Lead Developer > Rocket Software > -- There is nothing more pleasant than traveling and meeting new people!
