For the generalized trace facility (GTF), a response to message AHL101A or AHL102A, or a control statement in the GTF parmlib member, specified an incorrect value for the SVC or USR keyword. If SVC appears in the message text, an SVC number specified in the SVC keyword is greater than 255. If USR (user) appears in the message text, a user event number specified in the USR keyword is less than X'000' or greater than X'FFF'.
GTF ignores all options on the line in the response or control statement that contains the error. The system continues processing, but GTF initialization does not continue until the error is corrected. If the error occurred in the GTF parmlib member, the system issues message AHL124I to identify the error source.
In your reply to this message, correct the SVC or USR keyword and enter all options on the line again. If the error is in the GTF parmlib member, notify the system programmer.
If a GTF control statement caused the error, correct the SVC or USR keyword in the GTF parmlib member and restart GTF.
