Main Page

Welcome! This wiki documents RFO-BASIC! version 1.91, a BASIC interpreter that runs on Android, with a program text editor, that lets old-style programmers quickly write apps with access to most of the device's features, including web surfing, telephony, and texting. This manual is based on the published manual, plus comments the community has provided on the Forum.

Pages of this wiki will be written gradually and will be based on the existing manual, on personal observations, on study of the examples in the distribution kit, and on discussions on the Forum. Any given assertion might not yet have been reviewed by anyone with detailed knowledge of the code. It may give you additional insight but you rely on it at your own risk. This website is not complete until we say it is!

This wiki may also document new features, clearly labeled as "unimplemented," in order to get the user community to agree on their design and get them implemented in an orderly way.

To make suggestions or report mistakes, click on "Discussion" at the top of the article in question, to edit that article's talk page; or use the Forum. This is a wiki that anyone can edit. However, if English is not your native language, please comment on the Discussion page, adding links to relevant Forum discussions or bug reports, and allow me to shine it up.
