    ****************************************************************
    The 0C1 occurred in CSQRUE01's FRR when attempting to return
    to RTM by branching to R14 (which was incorrectly restored to a
    value of 0 following a call to procedure CSQWRCRD). This was due
    to R11 incorrectly being used as the save area; R13 has been
    used since v8.
    

Problem conclusion

  • Code in csqrue01.plx was changed so that R13 is saved in the
    main line and restored in the FRR as opposed to R11. Also, a
    line of code that set R13 to point at a different address to
    provide a save area for CSQWRCRD was deleted as there's no
    reason the main register save area cannot be used.
