The book says that the six commands DIR,ERA,TYPE,REN,SAVE and USER are 
available on any CP/M shell since they are implemented in the core (bdos 
?). All the other commands are external. DOS command.com kept the same 
idea for a long time, but added COPY and changed the syntax of a few 
commands.

And you are right, there is PIP, implemented as an external command. I 
did not use CP/M enough to become an expert at it.
