Yes but as I said again for the above (and the below) CURSOR is useless due to the problems with SCALE on non 2:1 screens, In effect you print in East and it ends up West :-) For a small gui like the one I am experimenting with, which relies on bitmap graphics, it is ESSENTIAL that the text goes where I want it, else you'll end up having windows that can't be resized but only in increments allowed by the OS. I believe that the trick is to utilise as much OS routines as possible (minimizing thus the amount of time for calculations) >If you have a POINT 50,50: LINE TO 100,100 then CURSOR >#channel,50,50,0,0:PRINT"Text" would position text at the 50,50 point. >To avoid overwriting the point, move the text a few pixels with >something like CURSOR #channel,50,50,10,10:PRINT"Text" > >I'm not sure if this is what you meant, hope it helps anyway.
