Since there is 256+ objects and under 512 (tiles) you should use 9 bit
long integers to get the information.

So what you might have is (this is presuming your using an unsigned char
type)

for (counter=0;counter<(7*10);counter++) {
	object_number = fgetc(in);
//	Your Function to put object_number into your object map object
possibly OBJECT_MAP[7][10]
	DoSomethingWithThisNumber( object_number, counter );
}

now if you were using 9 bit intergers you might be doing something like
this:

******************************************************
* 1  *  2  *  3  *  4  *  5  *  6  *  7  *  8  *  9  *
******************************************************
*   Object Number under 256                    * 1/0 *
******************************************************

so if bit 9 were 0 you would keep the number from bits 1-8 but if it
were 1 you would add 256 to the number from bits 1-8.  This just makes
the file size smaller but you could make it so that each tile takes up
two bytes of data...

I hope this helps
