Action=
	Gap
	~	
	~	The Flow is the difference between the DESIRED VALUE and the Current Value. Note \
		that this value may
		         be negative which will mean that the flow reverses direction.
	|

Gap=
	DESIRED VALUE - Current Value
	~	
	~		|

Current Value= INTEG (
	Action,
		0)
	~	
	~	Current Value begins with a value of 50 and is dependent on the rate of \
		flow.
	|

DESIRED VALUE=
	100
	~	
	~	The initial Desired Value is 75. At time 5 this increases to 100 and at time 15 it \
		is decreased to
		        50. This was done just as an example so the flow would be positive and then \
		go
		         negative....
