I have stepped through the code to check all of these issues and they are
not a factor (this is old code that is a hold over from pre-c++ days but the
function is basically the same).  As said in other post - this is run in DOS
and the names are always less than 6 chars + 1 '.' +3 extension char + 1
'\0'.



//CODE WHICH CALLS THE FILE OPEN FUNCTION
void write_data(int numstim)
{
  int ns,stim;
  for (ns = 0; ns < num_sub; ns++)
  {

   if (get_subj_fp(ns) == 1);//ERROR returns error which is ignored

   for (stim=0;stim<numstim;stim++)
   {     out_files[ns] << resp[ns][stim] << "\t" << resprt[ns][stim] <<
endl; }

   out_files[ns].close();
  }
}
