Erik, The source is in github : https://github.com/rscott-rocket/mxe
There was a matching Share presentation from Dallas 2020 that goes with it : Session 26556 z/OS Cross-Memory Server Code Walkthrough The main purpose was to show how to write a PC-ss and is probably way more than you need, but it will show the basics of what is required. I hope this helps - (warning I use IBM structured programming macros and some folks don’t like 'em).

So unfortunately our best (short time) option is to secure the SVC. I will contact you of list if that is ok about the sample code for a pc routine. Kind regards, Erik.
