Flow Blocks

	Loops specified number of times through enclosed blocks.
	Loops forever through enclosed blocks.
	If-then control structure tells the program to execute the enclosed flow only if a particular test evaluates to true (boolean operators used).
	if-then-else operator provides an alternative path of execution when the “if” statement evaluates to false, if so the program will execute the alternate path (boolean operators used).
	The while-do operator continually executes the enclosed flow while a particular condition is evaluated to be true.
	The until-do operator continually executes the enclosed flow while a particular condition is evaluated to be true.
	Waits for condition.
	Stops current loop or action.
