Programming

When

For

is executed, the variable value is compared to the end value. If variable does

not exceed end, the loop is executed; otherwise, program control jumps to the command
following

EndFor

Note:

The

For

command automatically increments the counter variable so that the

program can exit the loop after a certain number of repetitions.

At the end of the loop (

EndFor

), program control jumps back to the

For

command, where

variable is incremented and compared to

end

For example:

Displays 0, 1, 2, 3, 4, and 5.

Displays 6. When variable increments to 6, the loop is not executed.

Note:

You can declare the counter variable as local if it does not need to be saved after

the program stops.

:For i,0,5,1

: Disp I

:EndFor

:Disp i

i > 5

{

:For i,0,5,1

: --------

:EndFor
