CONTROL Statement
-
CONTROL variable <=values> <…variable <=values>>;
The CONTROL statement declares control variables and specifies their values. A control variable is like a retained variable (see the section RETAIN Statement) except that it is retained across iterations, and the derivative of the model with respect to a control variable is always zero.
