[comp.sys.mac] Porting IBM PC Applications

carlile@trwrb.UUCP (01/16/87)

(Is there a line eater?)

Has anyone had any experience in porting applications written in C on the IBM
PC to the Macintosh?  I'm not even talking about using any Macish thing here,
just porting something which runs on the PC and having it run, no matter how
ugly and PC like, on the Mac?  How big a problem is it?

A related, but completely different question, really for Larry Rosenstein.  Is
it possible to include C code in a MacApp design?  I want to do this if the
first question is possible, since the user interface is a lot simpler from
MacApp.

Thanks

MPW supports writing programs in a mixture of Pascal, Assembler, & C, so the
same it true of MacApp.  The only requirement of MacApp is that you write
the basic user interface part of your program in Object Pascal (or Assembler
if you prefer).  Internally, you are not required to use object-oriented
programming at all so you can use standard Pascal or C.

If you were going to port a program from the IBM PC, it should be easy to
keep the internals of the program unchanged, and use MacApp to construct the
standard Macintosh user interface.
