Sequential While

Definition

With this section you can repeat operations as long as a condition is met. (Can be called SeqWhile too)

Example

Thread 
{ 
    VARIABLE counter : INTEGER := 0; 
    While (counter < 8) 
    { 
        LED(counter) <= '1'; 
        counter := counter + 1; 
        Wait(1000); 
    } 
}

In this example, counter is counted form 0 to 7. The counter'th position of the LED vector is set high and between the loop there is a delay of 1000 clock cycles. Important: This loop won't repeat counting to 7, because the default value of the variable is only set at the verry beginning.
