Notice that pressing the I """Tl key followed by a key which has another character inscribed
above it. will enter the uppermost character. Thoe shift key permits two characters to share the
same button. and is sometimes called the "second function" key. Thus, in the first line of our
program (l ine 10 3bovel, a lSHIFTI keystroke followed by a
C±J
causes a
GJ

character to be entered. The entire line is stored in the computer as:

Good show! Our program is asking the user (you) for information necessary to perform the
task that we, as programmers. instructed it to perform. Recall the first line of o<Jr BASIC program
(which you .so kindly typed in for us) ;
OEG PAO I

The instructions within this line are currently being followed by the computer. The result is
that the computer is waiting for you to "input" (type in) some information.
This program will print a list of numbers ond their squares (the number multiplied by itself).
First, however, it asks the user how many numbers and squares to print !LIST SIZE?) . The user
!you again) responds by typing a number and pressing (you guessed it! I
(••r'"').
Type ([J and press
