I am using some code that will work somtimes less times than not,
anyway when it does chances are you cant continue in the game anyway,
the problem is that you save or load and dos gives you a big error
that just says invalid page fault and a lotta numbers.

the code that saves is as follows:

//////////////////////////////////////////////////////////////////////
// Author: Justin Hunt
// Version: 00.00.55
// Date: 29/03/2000
// Short Description: This is the finnally implemented saving script
//////////////////////////////////////////////////////////////////////
FILE * fptr;
int size1 = sizeof(player);
int size2 = sizeof(days);
int size3 = sizeof(stocks);
void dosave()
{
fptr = fopen("save.dat", "w+");
fseek(fptr, 0L, SEEK_SET);
fwrite(&player , sizeof(player), 1, fptr);
fwrite(&days, size2, 1,fptr);
if(ferror(fptr))
fwrite(&stocks, size3, 1, fptr);
fclose(fptr);
}


void doload()
{
fptr = fopen("save.dat", "r+");
fseek(fptr, 0L, SEEK_SET);
fread(&player, size1, 1, fptr);
fread(&days, size2, 1, fptr);
fread(&stocks, size3, 1, fptr);
fclose(fptr);

doprintbox();
	gotoxy(1,1);
	cprintf("You have");
        doprintbars();
      	gotoxy(30,2);
	cprintf("%d of 10000      ",player.stocks.gm);
      	gotoxy(30,3);
	cprintf("%d of 10000      ",player.stocks.ibm);
      	gotoxy(30,4);
	cprintf("%d of 10000      ",player.stocks.microsoft);
      	gotoxy(30,5);
	cprintf("%d of 10000      ",player.stocks.sony);
      	gotoxy(30,6);
	cprintf("%d of 10000      ",player.stocks.acer);
      	gotoxy(30,7);
	cprintf("%d of 10000      ",player.stocks.rogers);
      	gotoxy(30,8);
	cprintf("%d of 10000      ",player.stocks.shaw);
      	gotoxy(30,9);
	cprintf("%d of 10000      ",player.stocks.panasonic);
      	gotoxy(30,10);
	cprintf("%d of 10000      ",player.stocks.aol);
        gotoxy(1,11);
	cprintf("MONEY:%d         ",player.money);
	gotoxy(1,12);
	cprintf("Balance:%d       ",player.bank.balance);

gotoxy(30, 24);
cprintf("This is day:%d", days);
}

clearly this is in c but this will print some variables after it loads
all defined in other files that i dont want to post (TOO BIG)  any way
is it the structure that screws it up i have the latest djgpp 2.03 if
im not mistaken just downloaded it anyway.  This compiles perfectly
fine but errors as i say while doing it or likely right after.
