Up to Local Variables


Definition

The predefined local variable height is used in Mode7 windows, and it is assigned to each process. It is therefore only relevant in the coordinate system of mode7 (Ctype=C_M7). It is used to define the height of the process graphics in relation to the semi-3d field. This is not to be confused with the local variable Z, as that is used to control the depth of the graphical layers.

The height is normally a positive number, because the height of the bottom is 0, and all the processes are placed above it. When the height variable is not defined, it is 0 by default. The graphic base is placed at the indicated height, with the exception when controlpoint number 0 is changed (the default is overruled by the Center_set() function). In that case, the controlpoint will be placed at that height.
