App Description

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:
Commands:
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
Functions:
int() abs() sgn() rnd()
sqr() exp() log() log10() sin() cos() tan() atn()
len() val() asc() str$() chr$() hex$() mid$()
timer() date$ time$ pi
Operators:
+ - * / 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.
