How do I make text display on the top screen and touch screen?

"DISPLAY N" should be followed by "LOCATE" and "PRINT" commands. If you put text on top(touch) screen, you should set 0(1) as N. "DISPLAY 1" will be available while screen mode set by "XSCREEN" command is 2 or 3.

So that's how you display different text on the top screen and other text on tne bottom screen.

"DISPLAY N" should be followed by each "PRINT" as follows. ACLS:XSCREEN 2 DISPLAY 0:PRINT"top screen" DISPLAY 1:PRINT"touch screen" WHILE TRUE:VSYNC 1:WEND
