COBOL Manual for TNS/E Programs (H06.08+, J06.03+)

Debugging Programs That Use the TMF Subsystem
There are no debugging tools specific to TMF application debugging. You can use a symbolic
debugger to set breakpoints in both SCREEN COBOL terminal programs and in server programs.
If the symbolic debugger that you use can accept its commands from an OBEY command file, you
can create a script that interrupts transactions at various points in the requester and the server and
tests the recovery mechanisms.
