- It's a couple of years since I used REXX on a VM system so my experience
- may be out of date (Given the speed at which IBM moves, I doubt it:-)
-
- Rex did not have Regular expressions, or associtative arrays - two
- things that are the essence of perl. Nor did it have the direct access
- to system calls built in in the way perl does. Rexx is essentially
- general purpose macro language for some other interpreter, e.g. VM or
- Xedit.
-
- Rexx is OK so far as it goes, but , IMHO, not a patch on perl.
-
- BTW I saw a prerelease version of rexx on one of IBM's inhouse systems
- years ago, it had a nice interface for fullscreen aplications. I was
- most disappointed when the official release arrived with out it. Another
- victim of IBM's marketing machine, there were at least two VM products
- that would have been made redundant.
-
- Cheers, Russell.
