Hi.

I'm having a bit of trouble using binary streams via djgpp.
The code below (which I borrowed from the Borland support
site) serves to demonstrate the problem; with the MS or
Borland compilers, the two files are created as expected
(text.txt: 49 bytes, bin.txt: 47 bytes), but with DJ the
bin.txt file is empty.  Am I missing something?

Any help most appreciated...
