RT-11 was following standard DEC practice by using "." as its command
prompt.  The "monitor dot" was the command prompt in both TOPS-10 and
TOPS-20.

Most DEC operating systems, including RT-11, TOPS-10/20, and VMS, used
"/" as a prefix on command options; "-" performs this function on UNIX
since "/" is the directory delimiter.  Back in the days of stand-alone
programs, physical switches on the console were used to set program
options.  This of course won't work when you have multiprogramming.  I
was told that DEC chose "/" because it looks like a toggle switch.
Command options in fact were initially called "switches".
