QDOS was intended to be a clone of CP/M. PC-DOS had some significant differences form CP/M; I don't know whether that was true of QDOS.
I vaguely recall that CP/M had PIP with DEC syntax. -- Shmuel (Seymour J.)

The most important (IMHO) exception was lack of directories. BTW: I still have CP/M and hardware capable to run it ;-) First version of MS-DOS I worked consciously with was 3.30, however I had to do with some older version also. -- Radoslaw Skorupka Lodz, Poland ====================================================================== -- Treść tej wiadomości może zawierać informacje prawnie chronione Banku przeznaczone wyłącznie do użytku służbowego adresata.
