this is the first letter ever written on an Interim computer.

i spent many days and nights building this system, and i hope it will turn out to be useful in some way.

some helpful commands to get started:

(symbols) returns a list of all known symbols in the system. this list can grow quite large.
(ls) a shortcut to load the directory listing of /sd/, which is the boot disk (probably an SD card)
(import "/sd/editor.l") loads and compiles a text editor; or better, the text editing functions
                        (edit "some string"), (edit-file "/a/path.txt") and (edit-new)
(mouse-task) if you connected a USB mouse during boot, this helps you use it.
(load "/a/file") opens and receives the contents of a file as a byte array.
(def f (open "/a/file")) returns a stream handle to the opened file.
(send f "my text") writes (sends) the string "my text" to the opened file stream f.
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                        �
