General syntax

Discusses execute blocks.

A block of statements for preprocessing or postprocessing is marked by the keyword execute:

execute {writeln("Hello World."); } 

Execute blocks can be named:

execute HELLO {writeln("Hello World."); } 

Any execute block placed before the objective or constraints declaration is part of preprocessing; other blocks are part of postprocessing.

The scripting context within an execute block corresponds to the model declarations. You can think of the statements within an execute block being embedded in an IBM® ILOG® Script block named with.

 with (thisOplModel) {writeln("Hello World.");
}

where thisOplModel is the instance of IloOplModel representing the current OPL model.
