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: http://www.hotpaw.com/rhn/basic/iphone/ for a more complete description of the Basic language syntax, commands and functions which this Basic interpreter supports.
Updated for iOS 11 and the iPhone X.
Improved support for Larger Text (as set in Accessibility Settings).
Basic programs can now be downloaded to HotPaw Basic using iTunes File Sharing, or via the iOS 11 Files app.
The graphics drawing area is now limited to 80% of full screen.
This update includes bug fixes for entering quote marks, and for an occasionally missing "Stop" button to break program execution.

There's no Break!
How do you force a program to terminate short of exiting the app?
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!
Nice, but a few comments
Needs better docs on using some functions, especially the accelerometer, touch, and vibrate functions. Very cumbersome editor also. Overall a fun way to relive the days of old basic line numbered spaghetti code and to appreciate how good coders have it now!! Also crashes sometimes when getting out of the full edit mode. Hopefully subsequent releases will address some or all of these issues.
With Family Sharing set up, up to six family members can use this app.
