:= (Hot Variable Assignment)

Purpose:

Assigns a formula to a hot variable or Window.

variable := <formula>

variable	-	A hot variable or Window
<formula>	-	Any formula evaluating to a scalar, series, table or string.

Nothing, the formula is assigned to the hot variable.

a := 5

b := a * a

returns 25.

a := 10

returns 100.

W1 := gnorm(1000,1)

W2 := integ(W1)

assigns the formulae to W1 and W2.

See the = operator to perform a standard variable assignment. Standard variables do not propagate changes.

Use () to group multiple statements for a hot variable 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.

See == to compare two expressions.
