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.
