Hi Guys
I just downloaded he Bcc32 complier from Borland, Installed and set up the default option in the readme file
Then I got down to some coding
I have the complier running on Windows 2000 platform and running it under the command prompt nothing unusual I hope
The problem I seem to have is when I generate a large array using a for loop and process the data I can only use a small array ie 100 100 10 when I increase the size I get a program error and an error log has been generated (cant find where this is stored)
When I run a "mem" on my system I have 1MB total contiguous extended memory and 0 MB (zero) byte available contiguous extended memory (see attachment)
Can n e one shed some light on this I can see where I can go from here as DOS windows doesn?t allow you to increase memory
I've also tried using malloc() function to set the memory but i still get the same error(crash)
Here is the code using the malloc () function
Code:/*Snippet of code creates a 3D array*/
//Working version better that datacamera
#include "stdlib.h"
#include "stdio.h"
#include "math.h"

#define XDim 500 // this means X rows
#define YDim 500 // this means Y rows
#define size 2
#define index 0
main()
{
//printf("No Problem");
/*Initialisng the LOOP values x y and FrameNoDepth coordinates for the array*/
int i, j, FrameNoDepth,numberint;
double number;
int StartCount,EndCount,ResultCount;
printf("No Problem");
// Defines the datacamera array NOTE change to the datacamera that appears within the FOR loop
int *datacamera [NoOfFrames] [XDim] [YDim];
int *TotalDiff [size] [XDim] [XDim];
int *Diff [size] [XDim] [XDim];
datacamera [NoOfFrames] [XDim] [YDim] = malloc(2000000);
TotalDiff [size] [XDim] [XDim] = malloc(2000000);
Diff [size] [XDim] [XDim] = malloc(2000000);

printf("Allocation Error");
exit(1);
}

printf("Allocation Error");
exit(1);
}

printf("Allocation Error");
exit(1);
