st: gsort

["Metcalfe, Paul" <Paul.Metcalfe@nera.com>]

I am having problems with the gsort command and wondered if anyone on the
list can offer advice. The command normally works fine but a couple of times
Stata has supplied the following output:

gsort hid -time
variable __0000YG not found
r(111);

What does this mean?

Best regards
Paul Metcalfe
