Description:

See the Overview for a general presentation of the ILOG Script extensions for OPL.

Example:

For the following basic model:

float maxOfx = ...;
dvar float x;

maximize x;
subject to {
  x<=maxOfx;
}

and the following data:

  maxOfx=10;

Flow control script:

main {
  var source = new IloOplModelSource("basicmodel.mod");
  var cplex = new IloCplex();
  var def = new IloOplModelDefinition(source);
  var opl = new IloOplModel(def,cplex);
  var data = new IloOplDataSource("basicmodel.dat");
  opl.addDataSource(data);
  opl.generate();
  if (cplex.solve()) {
     writeln("OBJ = " + cplex.getObjValue());
  }  else {
     writeln("No solution");
  }
  var opl2 = new IloOplModel(def,cplex);
  var data2= new IloOplDataElements();
  data2.maxOfx=11;
  opl2.addDataSource(data2);
  opl2.generate();

  if (cplex.solve()) {
     writeln("OBJ = " + cplex.getObjValue());
  } else {
     writeln("No solution");
  }

  opl.end();
  opl2.end();
  data.end();
  def.end();
  cplex.end();
  source.end();
}

After execution the Scripting log shows:

 OBJ = 10
 OBJ = 11
