Definitions of Reason Codes (IORETRSN) for different return codes
(IORETCOD):
IORFRESN - Fatal reason code (IORETCOD = 12) IORCRESN - Cancel reason
code (IORETCOD = 20)
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.
