   A number of UNIX programs I have ported to OS/2 using emx or gcc
   choke on binary files, unless I modify them.

   for example:
   f = fopen(name,"r") must be changed to f=fopen(name,"rb")
   etc.

   I was wondering just what happens when you don't open as binary.
   Will it return EOF when it sees ^Z or what?

That's been my experience; I'm in the middle of porting a giant UNIX app.

   This is sort of troubling to me, since EMX is desing to make
   porting UNIX easier  Was fopen changed to make it more compatible
   with OS/2 or what. From what I've read "r" and "rb" are handled the
   same in UNIX.

The way I read K&R's 2nd edition, emx is correct.

Cheers, Lew
