Conversion Chart

[JB]

That is what I was using and it works for ascii to Hex, ascii to Binary,
Hex to ascii, Hex to binary, binary to ascii and then if you don’t have
a lot of characters and you only call it from one line it works for binary
to hex.  In other words don’t use if for binary to hex unless you only
are processing a few sets of 8 digit chars to hex and they are not
on different lines.  I even put them all on separate lines and only
took the eight chars so there were no returns to strip.  Any one
line out of many thousand will work but when you try to convert
another line it will not work but it might give you the appearance
that it worked.
