Rick, many thanks for this helpful information.
Les, I'm on Windows 7 and wish to control (in a rexx program) if the
current user has admin authorities before I start fiddling with things that
only such users can do. Of course I could attempt something and if it fails
assume the user is not an admin, but I'm more looking for a standard
isAdmin() function or similar.

Want excitement?
Manually upgrade your production database.
When you want reliability, choose Perforce.
Perforce version control. Predictably reliable.
