Explanation
During processing of a TESTAUTH macro, the system
detected incorrect input parameters, as follows: An incorrect bit mask is in register 1.
RBLEVEL=2, but the request block (RB) is the last RB chained or
is out of range.
The function code is greater than 256 or is out of range.
The authorization code is greater than 256 or is out of range.

System action
The system abnormally ends the program that issued
the TESTAUTH macro.

System programmer response
  If the error recurs and the program
is not in error, look at the messages in the job log for more information.
Search problem reporting data bases for a fix for the problem. If
no fix exists, contact the IBM® Support
Center. Provide the program listing for the job.

Programmer response
Ensure that the TESTAUTH parameter list
is valid.  The only valid IBM-supplied authorization or function code
is one (1).  If the installation supplied an authorization matrix,
check to see that the function and authorization codes fall within
the range of the installation-defined codes.
