                            Alpha Ver. 1.2

            Here it is, folks -- Tetris, written in BASIC, moderately
         playable, and under 1 kilobyte of code (engine only)!  And
         they said it couldn't be done!

            The original Tetrx 1K (alpha 1.0) was posted to ticalc.org
         a long time ago (several months now, I think).  This version
         speeds it up a bit (by getting rid of one Goto), and adds a
         "block drop" key.  Somebody PLEASE make the algorithm better!
         Basically, the engine has to get a LOT faster, and sideways
         collision detection has to be added.  That's a lot of work.

            The game still isn't fully functional, but it's close
         enough that I'm satisfied (for now).  If anyone wants to fix
         the remaining problems, go ahead...

             * There now IS a "block drop" (down arrow) key, but it's
                really slow; maybe a 50% increase in fall speed.  It
                needs speed.

             * Blocks can move sideways "through" each other, since
                there's no sideways collision detection (except the
                wall-related code, which won't work here).

             * Note that upon final release, TETRX.83P can be edit-
                locked (although I never edit-lock my stuff).  ZTETRX
                should remain "open" so users can edit the block
                descriptions if they feel so inclined.

             * Maybe different difficulty levels associated with
                different block sets?


            If anyone wants to fix these bugs/suggestions, be my guest.
         Please don't put (a) your name on it; (b) anyone else's name
         on it; (c) any code involving PICs, GDBs, or flashy intros,
         because I hate them; (d) anything involving Pokemon.
            If you manage a fully operable sideways-collision-detection
         system in under 1500 bytes, or have any questions, (but especially
         the former): PLEASE email me at "arthur_odwyer@yahoo.com".

            Thanks, and enjoy!

         (If you downloaded this file looking for an ENJOYABLE Tetris game,
         try Bill Nagel's ASM-based TETRIS 83Z.  It's much better as a
         game, but much worse as a teaching aid.  Why, the BASIC part
         isn't even optimized!  (And it's usually edit-locked, growf!)
         But it's a much better-playing game.)
