Re: QBASIC horror

Oh, the memories, QBASIC was my first programming language. It has been a very long time since I've touched it, and I may not remember correctly. However, I seem to think that QB uses pass-by-value by default, not pass-by-reference. This means that this bit: FUNCTION FOO (A, B) FOO = A + B FOO = TWI...

Your best bet is USB, actually. IEEE 1394 is Firewire400, not the newer Firewire800. At 400Mbps, that makes it slightly slower than USB2's 480Mbps.
