Changing The Atari 800 Cursor
I am working on a program for my Atari 800. I would like to know how to change the cursor from the ordinary box shape to a line. I saw this done in an adventure game and I thought it would be something nice to use in my programs.

You will need to write your own input routine which accepts keys from the keyboard, puts them into a string, and permits correction. Then, the cursor you use is up to you. Disable the system cursor with POKE 752,1.
You can display a graphics character on the line below the character it is highlighting. You could use a redefined character set, with patterns for letters with the cursor included (you would then alternate between the normal character and the underlined character). You could also use a player or a missile as a cursor (as done in "Scriptor," April 1983). There are so many ways to display graphics on the Atari that these suggestions barely scratch the surface of the possibilities.
