In the BASIC programming language, RUN is used to start program execution from direct mode, or to start an overlay program from a loader program.
The program is generally customizable through an extensive configuration file, and it supports color syntax highlighting for numerous popular file formats, a feature that is also configurable. JOE installs hard links and a set of rc files that configure JOE to emulate Emacs keybindings (when invoked as jmacs), Pico (when invoked as jpico), or ...
