switch & swith -globe question

Hello All,

 

 

Firstly I want to thank you for your help and suggestions. In that case (the last one ,Hoolio's suggestion I meant) I only compare the $trx with some strings A, B,C etc.

 

But What I really want to do is, comparing with the content of an external file Like "class match $trx1"does.

 

Is this possible?

 

 

Thanks a lot..
