Intrinsic Use
Error Handling
NOTE It is good programming practice to specify the status parameter and check
its value after an intrinsic call. If an error or warning condition is
encountered and the
status parameter was not specified, the intrinsic causes
the calling process to abort.
The
status parameter is read in two 16-bit fields:
Biots Value/Meaning
16:16
status.subsys : identifies the subsystem that initiated the error or
warning.
0:16
status.info : identifies the type of error or warning. Refer to each
intrinsic for possible values.
and represent the possible values returned by the
status parameter.
