Strcmp? Ugh, I suggest using ZCMD
Also.. You have formatted strings but not supplied any action?
I have cleaned up the code a bit, this should work now, haven't used strcmp for years though so mail me if this doesn't work and no one gets back to you because I am popping into town for a couple hours.
