Hi Walter, I have a problem with my pointer not incrementing
smoothly, one record to the next.  (see code below)
While stepping through an array and watching in the data/object
window, the following is happening. (Imagine array numbered 1 to 10)

records
1,2,0,0,5,6,0,0,9,10....etc.  So it misses some records yet catches
up, later. This is causing my pointer to go past the end of the array and
my program crash.

race_ctr = 0;			     /* find this race */
while( this_race_ptr->ref != this_run_ptr->ref
&& race_ctr < race_file_size )
{
race_ctr++;
this_race_ptr++;
}

The program compiles with no errors or warning messages.  It's target is Windows 95 and Console.

Maybe a clue here:  When trying to locate the bug, after assigning
"this_race_ptr" to the "racemem_ptr" (allocated memory)
the following increment statements had no effect.  this_race_ptr++;
(and the following) this_race_ptr += (race_file_size);  Yet on other
pointers in the same location (after declaration, not in while loop)
they work as they should?

I have attached the source file.

Any help very much appreciated.

Paul

I'd start by loading the program up with printf's to trace its execution.
