Hello Me again,

I found the cause of the gpf, something like this:

char s[3][4];
int  i,j;

for (i=0; i<3; i++)
  for (j=0; j<4; j++)
     s[j][i]=3; // Note I swapped the i and the j in this statement


But it was hard to find this error, cause when I had the
djgpp-environment variable on,
it didn't generate an error: IT all worked fine !!!!(Even the results
looked ok !)

Thank you for all your time and help...

Greets,

Rick Blommers
