Here's the portion of the code that I'm using. I don't
know if this is right. Please help.

*****************************************************
int _ctr0_startup_flags = _CRT0_FLAG_NEARPTR;

int main()
{
 unsigned long maxmem, f;
 char *x;

 printf("%s\n", (__djgpp_nearptr_enable()) ? "Enabled"
: "Disabled");
 x = (char *)(__djgpp_conventional_base);
 f = x[0x1000000];             // Both these don't
seem to work.
 _farpeekl(_dos_ds, 0x1000000); // Accessing 16MB

 return 0;
}
******************************************************

Thanks,
Prashant TR
