Sophisticated Total LCD Control
Now that we have an understanding of how to go about addressing the LCD, we can improve the routines that were created to make them more sophisticated and thus more useful. After we are done with the improvements, we will assign these methods to a separate file from where they can be called by all users and by all the procedures we create. This means that we will not have to include the methods as a part of our other programs. We will call these methods as we need them by including the relevant mother objects under the OBJ declaration in our programs. The new (8-bit) program, which lists all the new methods, is shown in Program 21-8.
