[net.micro.pc] Help with COMSPEC/COMMAND.COM

<<<>>>

The documentation for MS-DOS 2.0 indicates that one can change the file that
DOS uses when it has to replace the command interpreter (COMMAND.COM) if the
interpreter has been overlayed by a previous program. I need to do this 
because my current COMSPEC environment variable points to "\COMMAND.COM" and
when I run a program on my ram disk that overlays the command interpreter,
on exit I am unable to insert a disk with the command interpreter into the
ram disk since it it non ejectable. I could put COMMAND.COM on the ram disk
but that seems like a waste of space. I would assume that :
SET COMSPEC=A:\COMMAND.COM
should work but it doesn't (although it does update the environment space).
Does anyone have a solution to this? I tried a program called COMSPEC.COM
from dec-marlboro which is claimed to work for the rainbow but it doesn't on
my generic MS-DOS system. It seems that there are two COMSPEC locations and
when you use the SET command, it only updates one of them. Microsoft is
supposedly on the net, perhaps they can explain this poorly documented
feature.
