Practice with Screen Processing

In this lab we'll experiment with making a more interesting screen layout for the user. 

Some of the screen features of BLINK, UNDERLINE, HIGHLIGHT and LOWLIGHT are listed as valid commands but don't always work on every machine.  Write a test program to see if these features are available with the current configuration in the lab.  Write a program that displays something like "TESTING 123".  Edit the code and apply the different screen features to see if they work.

This will involve a SCREEN SECTION.    Also the code on pages 233-235 have sample code of a screen section. 

Don't forget to experiment with background/foreground colors, cursor placement, highlight, and blinking.
