Lurton, the first paragraph defines what it means for a character to be
considered "numeric" (zone of C, D or F, and digit of 0-9.  'G' is X'C7',
so it qualifies as numeric.

The manual seems a bit too clever here though.  I did a little survey
just now (sample size of 1) and 100% of the people I surveyed were
confused by this even though I specifically pointed out the definition
of "numeric" from the first paragraph.

I'll get the manual changed to say something like this for the 71-72
indicator:
  "The result field contains numeric characters; the low-order
   character may also be a letter from A to R, since these
   characters have a zone of C, D or F, and a digit of 0 to 9.".
