This document describes some of the internal structures used by OCP Advanced Art Studio. Description of OCP Art Studio's resource data format: buttons, menu items etc are defined in this way:
These data structures are collected into a list:

#Horizontal coordinates are in the range 0-639. These define a "resolution" equivalent to CPC's mode 2. The vertical coordinates are in the range 0-199.
#If this value is -1, then this indicates the end of the list.
#If foreground and background are the same, then no button is displayed
