Synopsis
Official Name: textShadow
Memory Address: 8508h
Length: 128 bytes.
This area of memory stores a copy of the large font text on the screen. This is used to allow the calculator to easily redraw the screen when you close a menu (by pressing clear or something.)
Note that textShadow doesn't neccesarily hold what is on the homescreen (although it will if the homescreen is active.) The homescreen text is backed up into cmdShadow if another application/context is active.
Comments
The large font text routines store to this section of RAM. To prevent this, reset appTextSave, (iy + appFlags).
