Without having your program its not so easy, but as everyone makes 
the same mistakes I'd say you did a wrong 'printf'- call:
Look at the following program, compile it,- you willnot  get 
a error, but when running you will get a strange result depending on 
your machine:

/* printf("%d  is the wrong call*/
#include<stdio.h>
void main()
{ double z1; /* you can use float z1; if you like */
  z1=32.3;
  printf("%d",z1);
}

If you change printf("%d with printf("%f everything will be fine.

BTW: If I take a float -variable instead of double the program 
displays 32.299999. Why?

Happy new year

P.S. I found SWORD in the DJGPP directory and installed it. Is there 
any English documentation, or why is it in French? What does SWORD? 
(Perhaps that's the reason why they've fired the atomic bomb this 
morning : To get simulation programm with a French documentation ...)'Bye, bye Mister Pride' (ABC, Night you murdered Love, Maxi)
