The “Output” command is a little tricky. Like the “Disp” command, the output command also needs quotes to print literal stuff like “calc4life”. Without the quotes, the calculator calculates c*a*l*c*4*l*i*f*e and prints it. “Output” can print text anywhere on the home screen (For more info about screens, goto   (another nerd joke) chapter 7). The home screen is 8 by 16 (8 vertical and 16 horizontal). The syntax of the “Output” command is:

:Output ( down comma right comma quote what you want to say quote )
The home screen and what “Output” looks like:

     
      1
      2
      3
    4
      5
      6
      7
      8 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6

                                                              The calculator first goes DOWN 8.  
                                                              Then the calculator goes RIGHT 12.
                                                              Notice how there is no “Done”.

You might think that “Output” is all that you will need (that’s what I thought), but that is not true. There is a key difference between “Disp” and “Output”. When you tell the calculator to display something, the calculator prints the text out and it recognizes that text or numbers exists on that line. So if you do “Disp” then “Disp” again, it automatically goes to the second line. Output doesn’t do that. Output is like paint. You paint it on the screen and it’s like decoration to the calculator. It doesn’t mean anything. It is as good as a blank space. That is why the calculator does not display “Done” at the end of the output program. The calculator “outputted” something, but it has no clue where after it executed the command. The calculator is afraid to DISPLAY “Done” (done goes to next line) because it is scared that it will ruin your output.

Storing is very easy:

:(value)variable

The value can be like ((A/B)+6). Just as long...
