Ah, yes, the hidden commands - those first three are very funny. I think Lock/Unlock editor have been mentioned before - I'm not entirely certain but I think they disable the CLI so that when you run your code from the editor you see it as it will be in the final exe.
As for these:
DRAW AT SYNC OFF%7646%0
DRAW AT SYNC ON%7647%0
CLEAR RENDER AREA%7648%0
RENDER CAMERA%7649%0
Well, I haven't really any idea but I'd hazzard a guess that the first two will trigger a "Sync" screen update whenever Sync On or Sync Off are called. Clear Render Area will probably clear the portion of the screen where 3d has been drawn - you can set the region of screen where the camera draws to using Set camera viewport, and add 2d sprites around it. You can possibly choose to clear just this area. And Render Camera probably simply draws the current 3d data to the bitmap, as happens in Sync - but minus any 2d in the scene.
I'll have to play about with these....
