        Why would I get S0C7 due to an invalid sign when I'm using PKA 
(not PACK) which ignores the original sign altogether and forces a 
standard positive sign on output?

        Why not?

        I can't do that because I'm using a generic, reusable routine to 
convert binary to zoned and it can't see the original record data.  It 
only sees the data I pass to it in a 64-bit register.  So the passed data 
has to already have the correct sign.


Sincerely,
