RTEM-11

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, especially when the program was run as a system job. The requirements for the changes and additions to the RT-11 code have been determined. However, the same program is expected to run under RSTS/E (using SWITCH RT11), 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 available concerning how RTEM-11 handles RT-11 EMT requests? In addition, does anyone know of any systems currently running which support RTEM-11 features which allow RT-11 programs to run in that environment? My assumption is that VMS on a VAX supported RTEM-11 at some point, but perhaps (if I am correct) the RTEM-11 support was not continued with more recent versions of VMS on the VAX and most definitely VMS on the Alpha. Can anyone comment on these questions? Jerome Fine
