The problem was very nearby. C2X() operated correctly on incorrect input.
Unfortunately, REXX provides little means to verify binary data other than
C2X() which was already under suspicion. My inclination (admittedly post facto)
would be something like:
call charout 'tempfile', dcollect.i, 1
address SH 'od -tx1 tempfile
... using a different utility for hex conversion of the immediately proximate
input to C2C().
