I might have missed a link in this thread, but I didn't see anyone point out 
the "a+" or "a" flag to fopen.  Someone gave a code snippet with "ab" in it, 
but noone pointed out the speed differential between reading every record in
the first file till EOF, verses opening the file for append.
I assume that MSDOS would lseek to the end of file.  Is that not true?
If our original poster is reading the entire file, as suggested by the 
great speed of "copy +" according to his comparison, then maybe all he needs
is the "a" flag, again assuming that it works.
