Calling all early-personal-computing fans, remember typing Basic programs into your home computer? HotPaw Basic recreates the retro-experience of a text-mode Basic interpreter, and it runs right on your iPhone or iPad.

You can also use HotPaw Basic as a programmable calculator, or for displaying simple line graphics.

The HotPaw Basic interpreter supports the minimal Basic language, including:
let if then else endif dim data read restore
for to step next while wend goto gosub return
? print input open close end stop mat
run new list del save load dir cls rem
int() abs() sgn() rnd()
sqr() exp() log() log10() sin() cos() tan() atn()
len() val() asc() str$() chr$() hex$() mid$()
timer() date$ time$ pi
+ - * / mod ^ = and or xor not

Also includes new command and functions to support line graphics, Morse Code audio, FFT analysis, GPS location, MQTT and BTLE communications.

Line numbers are required. Type in the text of your program and type "run" to run them.

See: for a more complete description of the Basic language syntax, commands and functions which this Basic interpreter supports.

WOW! This is great!

I thought BASIC was gone. This is just what I've waiting for. I sure there's a compiler in the works, or at least a way to create an icon that will allow me to launch a BASIC program without having to load it manually. Great job on the app. Don't let it end here. Thank you.

Thanks so much for providing this! I've been looking for a BASIC that wasn't stripped down, be mobile for my iPhone, and was delighted this is it! I'm an amateur astronomer and I was using an awkward spreadsheet out in the field, which was cumbersome/very time-consuming to keep updated. Now I've written a program to handle it automatically. I spend more time preparing for my next viewing run instead of missing it! Thanks again!

There's no Break!

How do you force a program to terminate short of exiting the app?
