Subject: TSS Resource Class

I've identified several UR1 and UR2 resource classes defined within Broadcom
Top Secret (TSS), and they
appear to be configured for use. I'd like to confirm whether these resources
are actually being accessed.

I reached out to Broadcom, and they provided guidance on enabling audit
tracking and generating reports
using TSSUTIL. According to those reports, there is no indication that the
UR1/UR2 classes are currently
being used-but I'd like independent verification.

To test this, I've obtained a sample program that is intended to access a
UR1 or UR2 resource. The
expectation is that executing this program would trigger a security access
attempt (either permitted or
denied), which should then appear in the TSSUTIL report.

However, the program is abending with an S0C4, and my assembler experience
is limited-I can't determine
the root cause. I suspect the issue may lie in the RACROUTE setup or how the
parameters are being passed.

Would someone be able to review the program and verify whether the RACROUTE
is defined correctly or if
any required setup is missing?

Any assistance would be greatly appreciated.

Sample Program:

//SYSLIB   DD  DSN=SYS1.MACLIB,DISP=SHR
//         DD  DSN=SYS1.MODGEN,DISP=SHR
