About this helper

This browser-based BASIC runner helps test simple syntax ideas with a small BASIC-style interpreter. You can edit examples, run the whole program, or step through one instruction at a time while watching output and variables change.

Does the typed code leave the device?

No. The BASIC interpreter runs locally in the browser and does not send typed code to telemetry.

Which commands work?

The first version supports PRINT, LET, FOR, NEXT, IF, THEN, numbers, strings, and simple math.

Is this a full programming language?

No. It is a small interpreter for practicing variables, loops, and choices.
