Here is another table based scheme which combines sign validation,
sign classification (i.e., the sign is negative or positive) and
recognition of the preferred sign values.

Why would I get S0C7 due to an invalid sign when I'm using PKA
(not PACK) which ignores the
to be processed like a
zero. That works with NUMPROC(NOPFD) but not with preferred signs!

Dave,
I would consider using TP to verify the signs and protect yourself from
S0C7 on the subsequent handling of the packed number
also
I would not do anything against the number (no MHI or so)
- just EDMK it and place the sign(depending on the results of the
previous tests) where ever

I have to use PKA instead of PACK because the zoned data can be up

Regardless of pathlength or bytes for instructions - I like this most
Maybe add a comment to show that F becomes 7 and so on
and that invalid signs (0 thru 9 in left nibble) become ?

What is the shortest way (in terms of assembler instructions) to validate
these into just two classes --
You could use TRT to test the last byte, after some tedious coding of the
table. N.B. I mean using the table codes to identify +/0/-/invalid; not
just the 0/non-0 typical use.
You could PACK the field, or just the last byte (which is just a
nibble-swap), and CP to =P'0'. The cond. code tells

How about Compare Packed to a packed zero?
But doesn't "just two classes" overlook a third class,

It appears that the OP wants to "validate"; detect and
report the non-modal sign codes.
If the original is zoned it might require:
