| 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.
