hello on my pc home computer i have beebem-bbc model b/ master 128 Emulator and c64 forever i typed in his program into both computer`s
1 rem bbc 1
2 rem system$
3 for a = 1 to 500
4 print a
5 next a
run on both emulator and bbc was faster them any of the commodore from pet 2000 vic 20 c64 cbm 610,c128,c 16/plus 4,.... his program i found on a listing for apple iie any one who own bbc or any of computer i have list try it and see which one win ... and on all commodore i start program first by time c64 get to 99 bbc was on 200

just try on my brother 600 and bbc won it by time amiga was on 100 bbc was on 1000 i up for a = 1 to 2000

Crusty 8bit BASIC interpreters aren't a good indication of the speed of the machines they're running on. C64 BASIC for example was written for size, not for speed.

@mcbone

This doesn’t surprise me in the slightest. Although the BBC micros and CBM computers used the same family of processors the BBC's was clocked at twice the speed as the C64. That combined with the fact that the BBC micros probably had one of the best and fasted basic interpreters of the 8bit days means it was a very capable machine. The early models where hampered by the lack of memory though as they had a very memory intensive graphic system, unlike most machines of the time they could display different colours for individual pixels with no clash or limits bar only an 8 colour pallet.

@mcbone

I bet it will be slower on all systems, when you use floating point values, instead of integers.

Why would you use floating point? Of course there's no sensible answer, but on C64 basic, the default type is float.

So when you do f.ex. poke53280, 1, you're giving 53280.0f and 1.0f. Of course you can use integers instead (a%=53280: b%=1: pokea,b) BUT this will just slow things down, because in that case, the values will first be converted to float (before being converted back to integer internally).

Yes, that's really sucky design, but also (partially) explains the slow speed.

Of course every real programmer uses asm on every 8-bit platform, regardless how "good" the native basic implementation might be

Asm rulez!
I'm in VB6 now, and that really sucks. Not that it has anything to do with this though...

How fast? The above FOR loop would take exactly one second on my C16 according to my teenage time tests.
