Well I'm an old school C64 programmer, so let me ask you this. How do you write a program in BASIC that continues to loop and do stuff while waiting for a keypress? For example, I was trying to write a simple drawing program for the low-res graphics mode and I wanted it to blink the pixel it was currently sitting on when no keys were being pressed. How would I achieve this? On the C64 we would use a command like this: 10 GET A$: IF A$ =3D "" THEN GOTO 10 That would achieve the same thing as the GET statement alone achieves on the Apple, but I could remove that GOTO 10, and put it at the end of several other commands.. That way those commands would continue to execute until something was pressed. --- SBBSecho 2.12-Win32* Origin: Derby City Gateway (1:2320/0) SEEN-BY: 10/1 3 34/999 120/228 123/500 128/2 140/1 222/2 226/0 236/150 249/303 SEEN-BY: 250/306 261/20 38 100 1404 1406 1410 1418 266/1413 280/1027 320/119 SEEN-BY: 393/11 396/45 633/260 267 712/848 800/432 801/161 189 2222/700 SEEN-BY: 2320/100 105 200 2905/0 @PATH: 2320/0 100 261/38 633/260 267 |
