generated if an increase, or decrease, in the size of the IORBK should
have resulted in a change to the number of MVC or XC instructions
generated by the HCPIORCC macro.

Definitions of Reason Codes (IORETRSN) for different return codes
(IORETCOD):
IORFRESN - Fatal reason code (IORETCOD = 12) IORCRESN - Cancel reason

NOTES : All non-zero reason codes should be unique regardless of the
return code. This is because the return code may change without the
reason code being updated, which could lead to a misinterpretation of
the residual reason code if duplicates were defined.
