Multi-Valued Source Coordinates: The coordinate origin is specified by the multi-valued
source area start address. The maximum coordinate system size is represented by 1024 × 1024
positive coordinates, as shown in figure 4-3, but the size depends on the installed memory
capacity, screen size, and multi-valued source area start address. Depending on the multi-valued
source start address, this coordinate system may entirely or partially overlap another coordinate
system.
