Hi Clara -
If you issue a "snapshot" command prior to your "setbg" command, then issue
a "restore" command afterward, the state of the background prior to the
"setbg" command will be restored.

2. The program has a "sleuth" searching for a hidden
treasure. When he "finds" it through a
"colorunder" command, the program clears the graphics and
the player can start the game again with a new path. We only
are able to "dump" the grass on the page by using the paint
can. Of course, that ruins the "randomness" of the
program they have written.<br>
How can you program a page to fill with a "pattern" or
"rainbow" as a background for other images that will paste
on top of it?</font></blockquote>
