I am still not quite understanding the usage of Rexx variables with SYSCALL.
If myFileName = "/u/myfile" then do I want to code "SYSCALL open myFileName" or "SYSCALL open" myFileName ? In other words, does myFileName get passed by value, or does SYSCALL do an IRXEXCOM to find its value from its name? Ditto for SYSCALL write. The example on https://www.ibm.com/docs/en/zos/2.1.0?topic=scd-write shows "write" fd "buf" Which makes no sense to me at all. fd is passed by value but "buf" by name?

Well, I take that back. They show it in an if statement if SYSCALLS("ON") > 3 then ... which is more or less the same thing. The doc could be clearer, but I guess if all the IBM doc were clear we would not have IBM-MAIN. Thanks.
