Subject: LCD Driver Code

        Here's an LCD driver package that supports the 1x16 and 2x16
LCDs that use the standard Hitachi HD44100/HD44780 controller series.
 
        If you use this, you'll notice that calls are made from the
LCD.ASM to LCD_IO.ASM.  This isn't the most efficient way to do this,
but because of the number of platforms we develop on, we try to re-use
a lot of code.  With this method, we only need to tailor the IO.ASM
file to a particular platform.  In addition, we sometimes have the
real target platform, then a prototype that allows connecting an ICE,
so a version of IO.ASM is tailored to the prototype, and the linker
file specifies which one gets linked in.
 
        If speed or stack space are everything in your project, you
can copy the code from the IO.ASM file into the LCD.ASM.
