Expanding on what Phil said:
- Always put Address Command at the top of an ordinary Rexx
exec.
- Quote and capitalize all commands to the underlying system.
- Use the *full* CMS command
- Direct CP commands to CP via: 'CP whatever'
- Abbreviate CP commands that are inside of a loop to
improve performance. Ditto in execs that get used a *lot*
Unlike Phil, I think these *are* significant! They will
save you hours of misery and much embarrassment.

Ray, much nicer. Three nits:
1) DO FOREVER is usually preferable to DO WHILE 1 for readability.
2) ADDRESS COMMAND is usually preferable to ensure consistent operation: you
don't want things breaking because some user has a PIPE EXEC, for example.
3) Avoiding abbreviations is usually preferable for the same reason: you don't
want it to break because some user has a Q MODULE on their disk. (If they have
a QUERY MODULE on their disk, they're already confused by why it doesn't seem
to get invoked -- that's just how the CMS search order works!)
None of these are significant but since you're putting it out there as an
educational exercise...
