Yes, thanks. This is really just an example that represents my code. The
actual code is many lines now. Basically it compares each character of
the_text to the values from 0 to 255. This is, as I'm sure everybody here
knows, the same as 0x00 to 0xFF. For example sake, I only included the
condition that finds the 0xFF. Once I clean up my code I'll post it here or
somewhere so people can enjoy it - tearing it apart or marveling at it.
Either way it will be working at that point. (chr(0) is only part not
working yet.)

... I should have pointed out that this code was only an example to show the
comparison and what it printed out.
