Programs

AppBasic provides a multifile programming environment with programs taking the form of BASIC files placed in a directory named !RunImage. (The files are BASIC libraries, containing procedure definitions).

Converting !RunImage to a single file
It is very easy to convert !RunImage to a single file (and back again) using AppBasic's ‘Compress’ tool:

The !RunImage directory is renamed and can be removed when exporting the application.
