ngbasic

NG-BASIC is a BASIC interpreter written in Javascript. This means it is basically platform independent. Here are links to launch the basic interpreter as well as some initial information to get you up and running!

Notes
As suggested by reader Douglas, `Firefox users should disable the “Start searching the page for text as soon as I start typing” feature. If they dont, the first character they type into the window gets echoed properly to the screen but all chars after that one get captured by the find window that opens at the bottom of the screen and never make it to the Basic client window itself.

For quite some time, there also this irritating thing occured when, for instance, the ‘/’ key is pressed, as this opens the ‘Find’-dialog in Firefox-derived browsers. I figured out why it did this and this isn’t happening in version 0.2.14 (well, as long as you don’t keep it pressed).

I also ignore the F5-Reload key as to prevent an accidental loss of a (long) typed-in BASIC program.

Known Bugs

• Only confirmed running in Firefox 1.5.x, 2.0alpha1 and 2.0alpha2.
