Here I am!  jzick, what is the trouble you are having?

Here's a link to the code that jzick is talking about, along with the
discussion that prompted me to post the code:

For those who don't have access to MC's forums, here's the little program:

d valBegin        c                   x'+
d                                     00010203040506070809+
d ... add more lines for 101112 ... 808182 ...
d                                     90919293949596979899'
d valLast         c                   x'+

d lastByte        s              1a
c     *ENTRY        PLIST
c                   PARM                  charView  16
c                   PARM                  len        5 0
c                   PARM                  ok         1
 * Check the last byte for digit (0-9) + sign (A-F)
C     1             SUBST     charView:len  lastByte
c     valBegin      CHECK     lastByte                  11=FD
 * Check the first n-1 bytes for digits (0-9) in both nibbles
c                   EVAL      len = len - 1
c     valLast       CHECKR    charView:len              10=FD
 *
c                   EVAL      ok = NOT (*IN10 OR *IN11)
c                   IF        ok = '0'
c     'invalid'     DSPLY
c                   ELSE
c     'ok'          DSPLY
c                   ENDIF
 *
c                   RETURN
