Sure, TinyBASIC is a crap language, but maybe it somebody will go “heck! I need some sort of scripting for my gardening watering system so I can update it using a wireless terminal connection from my Android phone”

I guess the point of it for me is that there is 1,200 lines of hopefully the worst C you will ever see, that builds to 2,030 machine instructions and it implements something approaching a program editor and a programming language. Traditional flowcharts are the most “goto inducing” design method there is, and I have yet to see (common) CPU that doesn’t have a ‘goto’ or “jump” in it’s instruction set – even the humble “while” loop is actually hiding the real computer from you. They gain nothing from basic, on any platform. It already is a product for this audience. The Arduino platform already is a cheap way of learning embedded dev. You can do plenty of C or java (or whatever) on an old pentium II with modern software. There is also no reason to think that just because people are poor and can’t spend a lot on new big iron, they also need to be stuck with ancient software. Logic can be taught within a OOP paradigm just as easily without having to introduce ancient limitations, behaviours and methods. So “Basic build bad programmers” maybe an over generalisation, but it still has a lot of truth to it. Not that it can’t be done, but it is a waste of effort. That is because unlearning concepts now considered old is hard. There is a reason why education tools get rewritten every so often. It is obsolete and not an education tool. It’s fun for the odd hack or a drive down memory lane, But that is as far as it goes. But fondness of childhood memories does not mean that basic has a place in modern computing. I started out with P2000T, ZX spectrum and MSX so I stared out with basic just like you. I never used Z80 back in the day, but I would imagine something like this: Z80 would be a little shorter because it has more registers and can use double-byte instructions. Note that I’ve probably mis-remembered the syntax.

To make the comparison fair, we’ll assume that the assembler programmer is clever enough that they’ve managed to store both variables in the zero page to avoid complex addressing, and that the carry bit is already clear.

So let’s compare this with the equivalent native code for a 6502. And remember these are 16-bit variables, not 8. The variables would typically not be stored in registers on an 8-bit CPU (registers are precious, after all). In a typical 8-bit interpreted BASIC from the day, the line number and initial space would be stored as a single 16-bit unsigned integer, so your example line would be 7 bytes. Posted in Arduino Hacks Tagged arduino, basic, basic interpreter, c++, tiny BASIC Post navigation Right now, all we know is we’ll be spending the weekend digging through our copies of Dr. Tiny BASIC was originally conceived for the Altair 8800 that shipped with 256 bytes of RAM stock, so it seemed like a perfect fit. says he started this project to see how ‘old bearded ones’ conjured up so many impressive programs with a few kB of RAM. Not much, but more than the lowest-end BASIC Stamp. The BASIC interpreter eats up around 600 bytes in the Arduino RAM, leaving about 1.4 kB for BASIC code. Kernighan and Ritchie said themselves, “code involving a goto can alway be written without one” but found that using goto left a lot more room available for BASIC code.

True to Tiny BASIC’s assembler roots, ’s C port makes extensive use of the “infinitely-abusable” goto statement. The code is meant to be a faithful port of Tiny BASIC for the 68000, and true to Tiny BASIC form, it fits in the very limited RAM of the Arduino. Sent in a project he’s been working on – a port of a BASIC interpreter that fits on an Arduino.
