AT LOAD command (remote debug mode)

Gives z/OS® Debugger control when the specified load module is brought into storage. For example, z/OS Debugger gains control on completion of a successful C fetch(), a PL/I FETCH, during a COBOL dynamic CALL, MVS LOAD service, or EXEC CICS LOAD. Once the breakpoint is raised for the specified load module, it is not raised again unless either the load module is released and fetched again or another load module with the specified name is fetched.

You can set LOAD breakpoints regardless of what compiler options are in effect.
