Creating Programs
The steps you follow to create programs are:
Enter Program mode.
Enter the repeatable keystrokes.
Exit Program mode.
Run the program.
We will continue using the pipe area program to illustrate program-
ming concepts. As you were programming, you may have noticed the
numbers in the display. They are line numbers and keycodes.
Line Numbers. Line numbers appear left-justified in the display as
you are entering your program. The numbers, 00 through 99, are fol-
lowed by a dash. The dash separates the line numbers from keycodes.
Keycodes. The numbers to the right of the line number are called
keycodes. A keycode indicates which key you pressed. The first digit
indicates which row on the keyboard the key is in. The second digit
indicates which column the key is in. A line contains one or more
keycodes which together represent a single operation. Labels and
number keys don't appear as keycodes, but instead as A through F or
0 through 9.
