Filebrowser
Instead of using the command line or BASIC to load programs the decision was made to create a filebrowser that allows the basic functions to be performed.

It provides the basic functionality required to get minimum stuff done handling files. It is not much more than a rough hack, but works well enough for simple tasks.
Keys
| Key | Function |
|---|---|
| cursor up/down | move arrow up down |
| home / end | move arrow to first / last displayed item |
| cursor left/right | display next/previous "page" of entries |
| 0-9,A-F | change the "user" |
| L / return | load a file according to file extension |
| > | delete current file |
| K | copy a file |
| M | move / rename a file |
Caveats
File copying and moving (rename) will work by loading the file to memory and writing it back. This means these functions, as well as loading are limited to 51k of data ($cc00 bytes). Executeable file formats are described as part of main JAM information.
