How do I program joystick input in GW-BASIC? It's insanely easy in Applesoft: you use the PDL(0) and PDL(1) commands to determine where the stick is located along X/Y (0-255 on each scale) and then tell it what do based on those locations. For example, in Applesoft, my Lego robot navigation code looks like this: 3000 REM NEVIGATION 3010 FB=PDL (1):LR=PDL (0) 3020 IF FB < 75 THEN M=5 3030 IF FB > 180 THEN M=10 3040 IF LR < 75 THEN M=9 3050 IF LR > 180 THEN M=6 3060 POKE L,M: REM SEND COMMANDS (The variable L is the address of the interface card to the control box. The variable M gets translated into binary to turn the relevant bits on/off at the control box, which runs the motors, sensors, and lights.) How do I do this in GW?
