Hi,

Thanks for the help, but I'm still confused. Sorry to bug you, but 
could you please have a look at the following:

Memory configuration as reported by MEM:

    655360 bytes total conventional memory
    655360 bytes available to MS-DOS
    509200 largest executable program size

   4587520 bytes total EMS memory
   4046848 bytes free EMS memory

  15728640 bytes total contiguous extended memory
         0 bytes available contiguous extended memory
  10317824 bytes available XMS memory
           MS-DOS resident in High Memory Area

So, I have 16 meg ram right now, of which 4 meg is going to EMM386 
EMS.

Here's the output of my program:

Processing begins...
Available Physical Memory: 4345856
Available Virtual Memory: 117682176
File Length 1048576 bytes.
Available Physical Memory: 4333568
Available Virtual Memory: 117678080
Reading entire input file...
Calculating magnitudes...
Writing to output file...
Number of overflows was 0
Completed...

The first set of "Available..." is after a few lines of code but 
BEFORE any memory allocation.

The second set is after allocation of File Length bytes (1048576). 
Seems like not much has changed ???

Would you know what's wrong ? I just want to know how much memory is 
available to a call to malloc().

Thankyou for your time,
Pete.
