structure is IF something ELSE something else ENDIF
So you might wanna do:
Code:

IF INGROUP("ITDEPT")
USE T: "\\SERVER1\APPS"
ENDIF


IF INGROUP("FINANCE")
USE P: "\\SERVER3\ACCOUNTS"
ENDIF


IF INGROUP("SURPAC USERS")
USE G: "\\SERVER9\DATA"
ENDIF

If you wanna use ELSE, it should in this case be used something like this:
Code:


IF INGROUP("SURPAC USERS")
 USE G: "\\SERVER9\DATA"
ELSE
 USE G: "\\SOMEOTHERSERVER\DATA" 
ENDIF

This makes it that if you're in the group SURPAC USERS, g: gets mapped to \\server9\data, and if you're not in the group, it mappes something else to G: in this example.
