I'm trying to read a map from a data string. This is what I put to set the start and end of the loop. FOR MAP_X=0 TO 23 READ MAPCHECK$ (Later, I put NEXT some lines down.) The issue is the map is 42 characters long (0-41), but I can't put a higher max number than 23 or I get an error. I don't know what's going on. Can someone help me?

Never mind. I figured it out.
