: (Window Assignment)

Purpose:

Assigns a formula to a Window.

Window : <formula>

Window	-	A window
<formula>	-	Any formula evaluating to a series or table.

Nothing, the formula is assigned to the Window.

W1 : gnorm(1000,1)

W2 : integ(W1)

assigns the Window formulae to W1 and W2.

Use ()’s to group multiple statements for a Window assignment in an SPL routine. For example:

setw1()

{

W1 : (integ(gnorm(1000,1));label("Test Data"));

}

The setw1() routine assigns the formula:

integ(gnorm(1000,1));label("Test Data")

to Window 1 just as if the formula was entered from the command line.

The : and := operators are interchangeable for Window assignments.
