I am not expecting a whole crowd to respond, but even one
individual would be helpful.

I also realize that very few individuals even know about the
RT-11 Symbolic Debugger, SD:, which is a pseudo device
driver what is usually activated by a BPT instruction within
a user's program  - as opposed to having to LINK in the
ODT code.

If any reading this uses either V01.00 or especially Y01.16
of the Symbolic Debugger from V05.06 of RT-11, and
in particular the SDHX.SYS variant, I would appreciate
some feedback on some bug fixes and enhancements that
have been made.  Some include:
(a)  Saving Program Counter Addresses
(b)  Support to activate other selected jobs such as KED
       (ONLY jobs that do NOT enter SD:) while the user's
       job is stopped at a breakpoint
(c)  Single Step Mode to include checking on the Number
      of Stack Additions and Subtractions - in progress
(d)  Reduced Low Memory
(e)  Interactive SET commands for the "Symbol;V" commands
(f)  SET commands for Saving Program Counter Addresses
(g)  Help text for the enhancements
(h)  Any other enhancements that you can think of that can
      be implemented from a technical point of view - feedback
      will be very MUCH appreciated

All of the changes required more than three times the original
8192 bytes of extended memory required by Y01.16 of the
SDHX.SYS variant.
