00C12025

Explanation
While executing in the PSW key of the caller, an abend occurred during
an attempt to access the trusted user parameter that was provided by the caller.
This is probably the result of a logic error in the requesting program.

System action
The application is abended.

User response
A dump should be taken for problem analysis.

Problem determination
This reason code is placed in register 15 during any access to information
that was provided by the caller. When any abend occurs, this register indicates
which parameter caused the error.
