   -How do you use FSRead in newline mode?  It seems as if it should be
   -simple to read from a file, one line at a time.  Could someone please
   -send me an example, (I'm using Think C 4.0).

   You ask how you use FSRead in newline mode? Hah! FSRead has no newline 
   mode, bunky. You bite the bullet and buffer your i/o. Allocate a
   chunk 'o mem, FSRead into that, and move a ptr thru the chunk
   searching for carriage returns. When your ptr gets near the end
   of the chunk 'o mem, do another FSRead. 

   I glossed over a few details, but you get the picture. 

I believe this is wrong. When I wrote the MacNFS client, we had
serious problems debugging BinHex which used the NewLine mode of the
Mac File System. I believe you specify in the high byte of a parameter
to the open call or the read call the character to end reading on. In
your case this character is newline. Please EMail me if you can not
find the documentation, which should be in VolII. BUT, I am almost
certain this can be done!
