Your favorite hex conversion routine - ILE

I have a routine to convert a string of characters into a string containing
the hex codes for those characters.  If you feed it the string '123', it
returns the string 'F1F2F3'.  The routine utilizes a compile time table
that has 256 entries, each two bytes in length.  The value of each incoming
character is used as an index into the array to produce the outgoing character.

Since the routine only does array lookups by index, I perceive it to be
fairly fast.  However, I don't really care for the memory requirement of
this function, the CTDATA array takes 512 bytes, and of course all of the
data is in sequence.

If you have a favorite 'convert to hex string' routine, or perhaps there is
a nice bif already, please let me know about it.


Regards,
Rich
