Find the Characters & the PRGM Menu
Sometimes it feels harder to find the keys than to program the calculator.

The keys needed most often are the
ALPHA, in green, which serves as a shift to get to the letters and the quote symbol and the
PRGM, which is a menu and even when writing the program is used to get to the 3 program menus.

In the picture below, notice how many keys are needed just to produce 1 line of the program.

Again, in the picture below, notice how many times these keys are needed to produce the entire program.

The menus have been organized so the most frequently used keys are at the top of the list.

Input Stuff, Do Stuff, Store Stuff, Display Stuff

To the left, an entire program is displayed. The program computes the slope.

In order to create a program
1st: Press PRGM, to get to the program menu.
2nd: Curser over to NEW, to edit a new program.
3rd: Type in the name of the program. The APLHA shift is already set.
4th: Press enter to store the name and begin writing the first line of the program.

A program is designed to do stuff, but, often this requires the user to input information.

The INPUT command has two forms. For example,
INPUT A
produces a question mark on the calculator screen and sits there until the user inputs a number.
INPUT "prompt", A
gives the user a prompt then, produces a question mark on the calculator screen and sits there until the user inputs a number.


The Disp, display command, has two forms. For example,
Disp A
prints the value of storage location A on the screen.
Disp "prompt"
prints a text message on the screen.

To store a program, Press QUIT, above MODE.

Run A Program
To run a program:
Press PRGM, then the number of the program you wish.: This puts the program on the home screen just as any other command.
Press ENTER.: This executes the command to run the program.

In addition to the compute the slope program listed above, another page provides the code for a Solve Linear Systems Program.
