I once worked on a UV (SCO/Dell Poweredge) that was ported from a MCD that
had a lot of IF E = 401, IF  E = 201 etc. Come to think of it, every TCL
statement generates an ERRMSG. They're just not all errors. "100 items
selected" is stored in ERRMSG.

The ERRMSG dialect is evoked from the STOP databasic Statement. Does anyone
know of any other way to evoke ERRMSG text. I've often wondered.

thanks.
