Re: cvtch revisited

This error ("A domain error in a math function occurred") means that
the input data isn't valid hex characters, and therefore cannot be
converted.

In order to supply valid hex characters to the cvtch() function, the
source ("Src" in your prototype) must consist of:

* Each byte must contain an EBCDIC character containing 0-9 or -A-F.
* A-F must be in uppercase.


Note the last requirement.

Folks, I have posted code at http://code.midrange.com/6d4d39e9e7.html that
is intended to exercise the cvtch procedure (to convert hex characters to
the binary data they represent).



I have struggled with this instruction time and again over the years, and
always end up writing my own.  I was inspired and encouraged by Scott's
example here http://archive.midrange.com/rpg400-l/200205/msg00309.html - and
that does work great without changes on this system.  However, my code does
not, and I don't see gaping differences, aside from the length of the
buffers and so on.


(Note, there was much more to this program than what you see... but I have
stripped it down to this minimum-failing module in order to support the
debugging process.



The error experienced when running this on a V5R3 system occurs when
executing the cvtch() function:

Recovery  . . . :   Supply input values that are consistent with the

Would someone please enlighten me as to why I struggle so with this one?
Stragely enough, I never have such issues with cvthc.  Go figure.
