BITMAP AT #address
   BITMAP AT expression

This command can be used to change the starting address of the graphic screen, i.e. the video memory used by the chipset to draw graphics. On some chipsets it is possible to define the address freely, while on others only for specific addresses and, finally, still others do not even have bitmap graphics. For this reason, each platform will decline this value according to the set of possible values.
