   Dear reader,
   I encountered a problem with binary I/O using DJGPP for C. At this time I 
   cannot reach the website, and I am in a hurry to get an answer or an handle 
   where to look. I hope somebody can help me. Please answer to my email address 
   and not to the list, since do not read the list yet. 
   I write a number of doubles in binary format to a file. After a certain 
   number of numbers written on that file (binary) the information on the file 
   is not correct. In my test program this happens after 27 doubles written on 
   the file. In a larger program, this happens after 52 doubles. The larger 
   program works fine on a SUN workstation, so I guess my problem has something 
   to do with MS-DOS or the Gnu C compiler. Can somebody help me out of this 
   problem. Thans in advance, Dik Kettenis.

Please be more specific.  Did you open the file in binary mode?  Thus:


	fd=open("myfile", O_BINARY..., O_RDWR );


--OR--

	FP=fopen( "myfile", "rb" );

If so please post a code snip showing the open and write (or other I/O) calls.
