I always thought it was "Direct Draw" for some reason, i may have just 
come up with that myself.  Quick googling reveals:


"/ Actually, it stands for `Copy and Convert' and was renamed to `dd` 
only because `cc' was reserved for the C compiler! This is the authentic

PDP 11./"

Sounds believeable i guess....
