Introduction To BBC Micro Programming Using BBC BASIC - Part 2 - Conditional Instructions

In the second part of this series, Jason extends our knowledge of loops and introduces the concept of conditional instructions; if/then/else. We even create a simple number guessing game!

Worth to mention that there is a current operating system, called RISC OS, which runs on Raspberry PI and other ARM machines, which still has the BBC Basic Interpreter built in.

RISC OS runs on the pi? As in like an archimedes emulator? Any tips on how to do this? Would love to play Nevyron again!

Jason, four months ago I bought myself a BBC microcomputer. Please make part 3.

[@theprincessoftreeleaves205]

Thank you for the series, I'm looking forward to the part 3!

[@knightphantom3346]

Excellent stuff Jason, really great explanations of these concepts 👍👏. Where is part 3?

[@sexysensation]

Excellent series Jason, Thanks again.

[@SteveJohnSteele]

Is there more in this series? It's been 3 years.

Jason, it is as if you always wanted to star in that BBC computer education program, but were too young for that. When are the next parts coming? "Guess the number" was where I've got to in Sinclair basic, when I was 6, then lost interest. I've got a proper Beeb now.

Hey Jason, where is part 3?

[@BikerBytes]

Cut my teeth on a beeb back in the early 80s. Just the sound of the keyboard brings back memories ☺️

What went wrong the most? Power?

great video, well presented and clear to easily understand ,,fell like i was back at school again lol i even had the same lack of attention span , oops 5000 line for me ,10 print "pay attention wayne! "; 20 goto 10 ..

I would like to add one to my collection, but live in a 120v country. Is there any way to convert them to run on 120v power?

[@WistrelChianti]

Something I've yet to find the answer to (despite RTFM) is how to store something at a particular memory location, say FCC in hex. I know I can read with location%=&FCC:PRINT ?location (for example if we are going with a byte) but how to store something back there? Is it possible, or do I need to use assembly?

[@WistrelChianti]

Also is there a way to find the address of a variable in memory?

poke?

Sometimes BBC basic is really dirty: How to read a line like this: 1480 IF G%=128O RG%=129O RG%=240O RG%=241 =-1 ELSE =0 It seems to do away with OR or AND statements, THEN is missing, and even the place to put the -1 or the 0 in is missing.

Have the computer guess.
