"Instead, request clarification and hope he is one of those that think such a request deserves an answer"

The OP's original post:

"I've a string thats coming back from a microconverter. The string is stored in ASCII format, I need to store the HEX version of the string in a string"

The OP's clarification:

"OK I've a string which contains "$0#1"
I require a string which contains the HEX verson of this, i.e. "24302331" "

Do you really think this is insufficient information to understand what he is trying to do? Heck, I thought this was one of the clearest posts I'd seen in a while. He doesn't even use SMS...
