SMETANA

=======

Chris Pressey, 1994(ish)

* * * * *

A long time ago (about six years ago), I was writing some amusing notes

to myself and among them was an "algorithm that'll never fly," which

went something like:

1. Swap steps one and two.

2. Flap wings.

3. Go back to step one.

It then occurred to me that reducing this form to the absurd (removing

the "Flap wings" instruction) just *might* fail to yield a totally

untractable language.

I originally wrote the interpreter as a Visual Basic application and

named it SMETANA - both an acronym for "Self-Modifying, Extremely Tiny

AutomatoN Application", and a reference to the composer of the same

name.

The distribution available here is a much better implementation of the

SMETANA interpreter in a much more device-independent and scalable form.

I have retained the English syntax exactly. The program ends when it

tries to peform step number *n*, where *n* is one plus the number of

steps given in the source.

Syntax of the SMETANA Language:

    Smetana ::= Step {".\n" Step} ".".

    Step    ::= "Step" Integer "." (GoTo | Swap).

    GoTo    ::= "Go" "to" "step" Integer.

    Swap    ::= "Swap" "step" Integer "with" "step" Integer.

    Integer ::= "0".."9" {"0".."9"}.
