Next time you go into the editor, the copied region should show up on the destination page. For example, if you wanted to copy everything from X=0, Y=0, to X=16 and Y=32, copying from page 2 to page 4 with the top left corner being at 128,96, it'd be somewhat like this: GPAGE <displayPage>,2 GCOPY 4,0,0,16,32,128,96
