 The author provided us with the following notes and new version of
 the program:
 
-Here is a somewhat improved version of my tetris entry.  All the
-changes are in the `popen()` at the end.  Formerly a move was done
-to the HI score file which is not permitted for other users. Now
-other users can change the `HI` score file.  The extra option `-m` is
-passed to sort, so that it knows that its input files are already
-sorted.  The `-o` output option of sort is used instead of a
-temporary file.
-
-You may also want to consider giving just the raw option to `stty`
-at the start and `-raw` at the end. This further reduces the size of
-the program, but has the possible disadvantage that the program
-can only by stopped by 'q' or by the `kill -9' command.
