I have a think C problem. When I allocate the memory for the array
of pointers in allocatelandscape, it progressiveley slows down. 
This is a real pain as MAXSIDE is 70 and after 50 rows or so, it 
is *very* slow. The structure is too big for it to be declared as 
an array, so I have to use pointers to allocate the memory.

If anybody knows a remedy to this, please let me know.

Thanx a million --> rob

Here's the source:

#include <stdio.h>
#define MAXSIDE 70

typedef struct {
		short food; 	
		short restorefood;
		short org1, org2;
		}squaretype;

squaretype *landscape[MAXSIDE][MAXSIDE]; /* global var */

void allocatelandscape ()
{
	int x, y;
	
	for (x = 0; x < MAXSIDE; x++){
		for (y = 0; y < MAXSIDE; y++)
			landscape[x][y] = (squaretype *) malloc (sizeof(squaretype));
		printf (".");}
}

main ()
{
allocatelandscape ()
}
