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:
Ê 
Displays 0, 1, 2, 3, 4, and 5.
Ë 
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.
