These are some of my first attempts at assembly programming.  It seems to me
there are an awful lot of restrictions about which registers can be used for
which purposes, but there are several ways around those.  I tried to pack
as many features as I know how to use in these two programs, and I hope that
any other beginning assembler programmer finds the source files useful for
techniques that aren't readily apparent (unless you're following Chris Fara's
Assembly Language Tutor series in Computer News 80).

The features to look for are:

   > macro instructions
   > lookup of a value in the system FLAG table
   > scanning a table to find a specified byte value and its position
     within the table
   > establishing a "mask" and overwriting it with retrieved data
   > displaying a symbol from the Model 4's special character set
     (like a copyright mark or a hand with a finger pointing
      to highlight a menu selection)
   > employing a user-entered number from a menu as an index to obtain
      a value from a table

Feel free to comment on my lack of style; it's the only way I'll learn
to do better.  (Take it easy, though.)
