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:
W1 := (integ(gnorm(100,1));label("Test Data"));
The setw1() routine assigns the formula:
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)
