Sample program

    Here's a simple example. It will display the sum and difference of two numbers. Press New, then press...

Read	Read a number from the keypad into the register
Store A	Store the contents of the register in bucket A
Read	Read another number from the keypad into the register
Store B	Store the contents of the register in bucket B
Load A	Copy the contents of bucket A to the register
Add B	Add the contents of bucket B to the contents of the register
Write	Write the contents of the register to the display
Load A	Copy the contents of bucket A to the register
Sub B	Add the contents of bucket B to the contents of the register
Write	Write the contents of the register to the display
End	Stop execution when you get here

    Key point: Every operation uses the register!

Running it

    You have several options for running your program...

Run	Run the program, stopping only for Read statements. Continue running when the user presses Enter on the keypad.
Step	Run the program one line at a time. Press Step after each instruction. A great way to learn! Watch the register and watch the buckets!
Stop	Stop the program wherever it happens to be. The program will remain in the code display.
New	Clear everything and start a new program.
