I have a fair amount of experience writing assembler and calling it from Rexx.
Is your problem with "getting going" -- the linkage and that sort of thing -- or some logic problem in your assembler once you get going? You might try writing the world's simplest assembler program first -- maybe just do nothing except survive the call and return successfully. Get that working. Then enhance it to return 'Hello, World!" in the result area. SAY it from your calling Rexx to make sure you got it right. And then move forward one step at a time. You have two "non-debugger" options for debugging: 1. WTO's. Good especially for tracing how far you got in your logic. 2. The old DC H'0' and debug from the dump.
