Yes, but there is no equivalent of "cd .." with PREFIX. E.g., if I
am in /HD/PERSONAL/LETTERS/JOE and want to see letters to Bill, I
have to type PREFIX /HD/PERSONAL/LETTERS/BILL whereas in Unix I
would simply type "cd ../bill".

FP and INT have always been part of DOS 3.3, to the best of my knowledge.
