I have fixed some of the bugs in a program which runs under RT-11
(obviously using the
PDP-11 instruction set - since actual DEC PDP-11 hardware can be
replaced by either
other compatible hardware on an emulator such as SIMH or E11).
The bugs were causing problems when the program was run under VBGEXE,
when the program was run as a system job.
The requirements for the changes and additions to the RT-11 code have
However, the same program is expected to run under RSTS/E (using SWITCH
TSX-Plus (which is fully compatible) and RTEM-11. It is this last
expectation for which I
have been unable to find any documentation, let alone any ability to
test the program. Does
anyone who is reading this know where there might be documentation
how RTEM-11 handles RT-11 EMT requests? In addition, does anyone know
systems currently running which support RTEM-11 features which allow
to run in that environment? My assumption is that VMS on a VAX
at some point, but perhaps (if I am correct) the RTEM-11 support was not
more recent versions of VMS on the VAX and most definitely VMS on the
anyone comment on these questions?
