Several things I discovered. My old REXX COMPILE EXEC…doesn’t work on VM/370CE and DOS/VS as written! I was using a newer VM and DOS, probably SP. I discovered the QUEUE statements require the string to be 80 characters. So I must pad them first. I also found that the EE editor doesn’t create fixed length 80 character files. So if I submit them to DOS they fail. I assume the problem is with the old DOS and not REXX. At any rate DOS/VS expects a lrecl of 80.
