Thanks for the reply, Nick.
I looked up the paste sprite command in the help but it appears that all that function does is relocate a specified sprite. I am already doing that with the sprite command in my drawing sub (Although I will probably now change to paste for speed reasons since it is solely for relocating whereas sprite is open to specifying a different image etc...)
However, my problem is that I am trying to get text, as in, output from the text or print command to appear over the top of a sprite in the background. Take for example, if you have a full screen size permanent background sprite, which gets refreshed every cycle - how do you get the text to be readable ABOVE that, rather than somehow be wiped out every frame? I was thinking along the lines of some sort of priority setting option, but the only one of those I could find that was relevant applied to sprites as well...
