Heya,
 I have a struct which looks like this:
typedef struct Map {
	int w, h;
	char name[8];
	BITMAP *tiles[60][60];
} Map;
 So far, I've just been expirienting with drawing and scrolling the Map
around the screen, but now I want to add loading/saving routines , and make
a shoddy map-editor :). Right now I have a saving routine which looks like
this:
	
	Map *m;
	pack_fwrite(m->name, 8, fl);
	pack_iputw(m->w, fl);
	pack_iputw(m->h, fl);
	for(x=0; x< 60; x++)
		for(y=0; y< 60; y++)
			pack_fwrite(m->tiles[x][y], sizeof(BITMAP), fl);

And a loading routine which looks like this:
	Map *m;
	pack_fread(m->name, 8, fl);
	m->w = pack_igetw(fl);
	m->h = pack_igetw(fl);
	for(x=0; x< 60; x++)
		for(y=0; y< 60; y++)
			pack_fread(m->tiles[x][y], sizeof(BITMAP), fl);

... Of course, whenever I try to load a map I've saved, the program crashes
a horrible death :). Any help is needed and appreciated!
thanks,
chris
