For Color Basic on the COCO, the line pointers in a saved basic program 
are ignored because the program may not load to the same address it was 
saved from. Instead, after the program loads, it scans the program and 
recalculates all the pointers. As long as the pointer isn't zero, it 
probably doesn't matter much what it is in that case.
