L	¾	Begins a new equation, turning
		on the "¾" equation–entry
		cursor. Lturns on the A..Z
		annunciator so you can enter a
		variable name.
V d	#/¾	LV types # and moves the
		cursor to the right.
.25	#/)_	Digit entry uses the "_"
		digit–entry cursor.
zNz	#/)ºπº¾	zends the number and
		restores the "¾" cursor.
LD 2	#/)ºπº: _	types :.
zLL	#/)ºπº:º¾

‘#/)ºπº:º Terminates and displays the equation.

 /	Shows the checksum and length
/	for the equation, so you can
	check your keystrokes.

By comparing the checksum and length of your equation with those in the example, you can verify that you've entered the equation properly. (See "Verifying Equations" at the end of this chapter for more information.)

Prompts for variables on the right–hand side of the equation. Prompts for D first; value is the current value of D.

Enters 2 1/2 inches as a fraction.

Stores D, prompts for L; value is current value of L.

Stores L; calculates V in cubic inches and stores the result in V.
