Each user needs a PRCLM quota sufficient to create an additional
    process for the debugger, beyond the number of processes needed
    by the program.

    BYTLM, ENQLM, FILLM, and PGFLQUOTA are pooled quotas. They may
    need to be increased to account for the debugger process as
    follows:

    o  Each user's ENQLM quota should be increased by at least the
       number of processes being debugged.

    o  Each user's PGFLQUOTA might need to be increased. If a user
       has an insufficient PGFLQUOTA, the debugger might fail to
       activate or might cause "virtual memory exceeded" errors
       during execution.

    o  Each user's BYTLM and FILLM quotas may need to be increased.
       The debugger requires BYTLM and FILLM quotas sufficient to
       open each image file being debugged, the corresponding source
       files, and the debugger input, output, and log files.
