Some intrinsics use the status parameter to return information on the status of the intrinsic call (refer to the MPE/iX Intrinsics Reference 
Manual (322650-90028), for further information on this feature).
The status parameter contains a number representing the subsystem that initiated the error or warning.
Table 1-1 “Status.subsys Parameter Identifiers” represents the possible values
returned by the status parameter.
