Okay, so how would I define the array? (I told you I'm a newbie. :)

Sorry, misworded question on my part.  It should have read: How can I
return back to a specific point in a function AFTER calling another
function?  I.e. main() processes some stuff, calls temp(), then temp()
processes some more stuff, then returns to a point where it left off
in main().

Allright.  Now can you point me in the direction of some sample dirty
rectangles code?
