[Tutor] RE: Why MS chose \

Having digest problems so answering this indirectly...

My understanding of the reason for the choice of \ was 
that / was already in use. MS DOS(and its precursor) were 
originally cheap clones of CP/M and CP/M programs 
conventionally used / for command line options.
(CP/M didn't have paths as we know them...)

Thus when MS had to introduce paths(DOS 2?) they chose 
the opposite form of slash.

I just checked and certainly the CP/M assembler and 
MBASIC interpreters both used '/' for commandline options 
as did the original CP/M wordstar. So it sounds reasonable.
