I don't understand the problem...The code in your first post should work just fine and so should that in your latest post - have you actually TRIED this or are you just thinking to much ;-)

myArray[0] = "H"

If myArray[0] = "H" THEN...
or
If myArray[0] = 72 THEN...
or
If myArray[0] = 001000 THEN...
or
If myArray[0] = $48 THEN...

Same thing as in my previous response - they are all the exact same thing just expressed in different ways.
