SETHOTVARIABLE

Purpose:

Sets a hot variable.

Syntax:

SETHOTVARIABLE("name", value)

"name"

-

A string. The name of the hot variable.

value

-

A string, scalar, series or table, the value to assign.

Example:

sethotvariable("RateOfChange", deriv(w1))

 

sets the hot variable, Rate_Of_Change, to the derivative of Window 1. Whenever Window 1 changes, the hot variable, Rate_Of_Change, will be updated.

Remarks:

Hot Variables are linked such that if the dependent value changes, then the value for the hot variable changes.

 

Hot variables can also be assigned with the syntax:

 

RateOfChange := deriv(W1)

 

 

A Window formula can also be assigned with the := syntax.

 

W1 := gnorm(1000,1)

 

This form is useful in SPL routines that must set explicit Window formulae.

 

SETHOTVARIABLE can be abbreviated SETHOTVAR.
