RFO BASIC! is a dialect of Dartmouth Basic that allows you to write and run programs directly on your Android device.

There is a 150+ page manual available in pdf and docx format.

In addition to the traditional Basic features, your have access to:

Graphics (with Multi-touch),
Build User Interfaces with HTML and JavaScript,
Device Sensors,
Music Play,
Text to Speech,
Voice Recognition,
Sound Pools,
Audio Recording,
Tone Generation,
Data Structures such as:Array/List/Stack/Bundle
Internet Browsing,
Text and Byte file I/O,
User defined functions,
FTP Client,
TCP/IP Client and Server Sockets,
Send and Receive SMS Messages,
Send Emails,
Make a phone call,
Superuser access

BASIC! programs may be packaged into applications. There are two processes provided for this. One process generates a home screen shortcut but requires BASIC! installed to run. The other process generates a stand alone application that does not need BASIC! installed. The resulting application can be offered on the Android Market.

All of the features of BASIC! are documented in the manual, De Re BASIC!, which is currently over 150 pages in size.

The install package includes over three dozen BASIC! source code files that explain and demonstrate the implementation details of this dialect.

BASIC! is being continuously improved. Many of the improvements have come from user requests. Also, since BASIC! is open source, others have begun on the code. Join the BASIC! forum and become part of the development team.

Permissions: This application asks for many permissions. None of permissions are exercised by BASIC! on its own. They are only exercised if you, the BASIC! programer, writes a program that exercises them. For example, BASIC! will never intercept a SMS message unless you use the SMS commands in a program that you write.

    Well documented product with lots of examples of code.. If you also get Basic! Launcher on your PC you can code and test with a proper keyboard and see your results on your device over USB. There is also an android app Basic! Launcher which will give you a WiFi connection to your pc for most setups.

    When I attempt to download the documentation from the site the app refers me to, I get access denied messages. What could be the reason for that? Why would the dev not disclose the documentation? What could be in there that (s)he doesn't want people to know? Therefore, 1 star rating.
