I managed to dodge the RSX Queue Manager 1993 bug this morning.
Note dodge, not fix. This bug isn't fixable in any practical sense. Here
are some hints that may be helpful for you do-it-yerselfers (your mileage
may vary, no warranty expressed or implied, etc. etc.):
In modules QMGGTI.MAC and SHOWP.MAC (UIC [25,10]), you will find a
small number of occurances of the constant "77.". It is added to or subtracted
from the year, in an attempt to encode the year as a 4-bit quantity. Since
93 - 77 = 16, this scheme fails. The dodge is to change 77 to a larger number
(I used 87, but anything from 78 to 93 should work), and rebuild QMG and QMGCLI.
Be careful to change only the occurrances of "77." that are related to the year
calculations - don't just do a blind global replace.
I observe that this scheme might self-destruct on Jan 1, 2000,
as well...
This fix was for RSX 11M-PLUS V4.00, BL40. If QMG was changed since
then, all bets are off (see disclaimer above). If you break your system, I am
not responsible.
Good Luck.
