[comp.sys.mac.programmer] MPW Pascal Units

franklin@uvicctr.UVic.CA.UUCP (Katherine Franklin) (02/28/90)

Hi,

I'm just getting started with MPW Pascal and Mac programming and I'm
having a hard time figuring out how units work with Pascal with makefiles
and linking. The Pascal manual doesn't seems too helpful, but maybe I just
don't know where to look. I would appreciate any help in answering my
specific question or in any good references for finding out the answer
myself.  Here is my question:

Unit A uses Unit B. Unit C wants to use Unit A, but wants A to use a 
different implementation of Unit B (interface is the same). Is it possible 
to link, use makefiles, etc. to substitute a different implementation of 
Unit B without affecting the contents of Unit A, or the original Unit B ?
Note: Unit A, and both B's are my own creations.

	Thanks,
	  Katherine
