BB___BACKGROUND

=BACKGROUND= toc

Description
> A Background is a bitmap image. It can be created at runtime or loaded from an external BMP file with the LOADBMP command. > The command expects a handle of the bitmap, and not a path to an external file. > The Background and Sprites will not show up until a DRAWSPRITES command is issued. The background can be changed at any time.

 * 1) Print #Handle.Extension, "Background BMPHandle"
