I use Citrix too and need to do something different if the client is a Citrix user. I tried using the WTSVR option and could not get it to work. But cj's example did work.

IF LEN("%winstationname%")>1
;do something
ENDIF

It seems like using the WTSVR option would be better. Perhaps I was using the wrong syntax. Could you please give an example?

Thank you,
Rebecah
