Determining the computername of a computer through logon script using multiple if statements

Hi guys!

Hope you can help.

We have citrix users that are located in different states throughout Australia.
What I need to do is to determine the first 3 letters of their computer name when they logon to a citrix server, so as to run different parts of a batch file (logon script).

So, the batch will be something like:

IF %COMPUTERNAME%==MUL* goto
IF %COMPUTERNAME%==SIL* goto y
IF %COMPUTERNAME%==ASQ* goto z
else goto end:



:x


:y

:z

:end

Im pretty sure you cant use a wildcard statement with the IF statements.
Can anyone lead me in the right direction please (would really appreciate it).

Thanks guys.

Simon
