Editing Variables

The FOR NEXT loop is a way of making a certain action occur a set number of times.
Sometimes it is necessary to change something each time the action is performed.

One way of doing this is to use a ''variable''.
A variable is a word which can be given a numerical value.
Try this example.
From the Smart Move main screen type LET cars = 23 < Enter >, then type PRINT cars < Enter >.
The current value of cars (i.e. 23) will be printed.

The example shown in fig. 4 uses a variable to switch on and off each output in turn.
Type BUILD FlashThemAll < Enter > and type in the lines shown in fig. 4.
Then press the < Esc > key to display the main screen.
Type FlashThemAll < Enter > to run it.

''How it works.'' As you can see variables are an important feature of Smart Move.
Your variables can be up to 15 characters in length.
The command VALUES will list all the variables you have created and their current value.
