In RSX-11M-PLUS V4.3 you should modify the following 4 files:
QMGDA2, QMGGTI, QUEAFT and SHOWQ (all in [25,10])

Replace "77" with something appropriate.

This will fix the bug in all practial sense. It will break again when
you pass the 16 year limit, but I suspect most stuff will break by the
year 2000 anyway.

Well, the same applies to my notes. This for RSX-11M-PLUS V4.3 BL66.

I don't understand what you mean by dodge. Maybe we're talking the
same thing, but by fixing the four files I mentioned above, everything
will work exactly as expected to, and as they should, and did before
1993.
