It's been a long while since I dabbled in REXX - I really like it, BTW.

These are just program calls - are there any examples of calling APIs from REXX? One question is, how do you pass a binary value in the data-type-less world of REXX? A number of these parameters are 4-byte integers. And is there anything like a global error handler - again, I've been away too long.

You pass a binary value in Rexx much the same way as we used to do in CL before the %BIN function and recent data type support. Use a character field and the C2X function or similar to populate it.

BTW, one thing I left is checking a variable in case an error occurs in the error handler, so as to avoid a loop. This may or may not be an issue in REXX.

It's an issue in all programming languages. Any generic error handler must handle the case where an error in itself causes recursion.
