Actually the reason MSDOS used backslash was because it had already used 
the forward slash for a switch-character.  Then for version 2, with hard 
disks being supported for the first time, they used the backslash 
instead.  At the time I talked them into supporting a "switchchar" call 
to change to using the dash for switch character, and slash for 
subdirectories.

But the idea was never publicized, so it never caught on.  And future 
versions of utilities generally paid no attention to the value of 
switchchar.

By the time Windows split off from MSDOS (NT 3.1), the support in the OS 
for both slash and backslash was well established.  But the utilities 
never grew up.

Yes, using the slash as a switch-character was inherited from CP/M, 
through QDOS, then MSDOS.


On some of the old teletypes, if the data was coming in fast enough, you 
could see the first character of the next line printed before the typing 
element reached the left margin.  So newline was then spelled CR/LF/NULL 
  or even  CR/LF/NULL/NULL

Buffering?  What's that?
