Assigning Window Formulae

 

The := operator can also assign a formula to a Window. For example:

 

W1 := gnorm(1000,1)

W2 := integ(w1)

 

Assigns and evaluates the formulae for Window 1 and Window 2.

 

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

 

setw1()

{

    W1 := (integ(gnorm(100,1));label("Test Data"));

}

 

The setw1() routine assigns the formula:

 

integ(gnorm(100,1));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. For example, the statements:

 

W2 := gnorm(1000,1)

W2 : gnorm(1000,1)

 

are equivalent.
