I have never done any programming on the Amiga, I want to start though. I will have a look at Blitz Basic.
Heinz: Is that programme in C? What does it do? I can see it has something to do with the parallel port but exactly what I'm not sure.
So far on the PC I have been making various combinations of LEDs light up by typing 'OUT 888,255' in Quick basic, where 888 is the address of the data register and 255 is the value to send to make the LEDs light up.
