ALIASES

From ASCEND

The ALIASES statement is used to create a local alias of another variable elsewhere in an ASCEND model. You might for example have a complicated object-oriented model containing some important variables nested in a sub-MODEL. Using an ALIASES statement you can pull out that nested variable and make it more visible by being available in your top-level model.

pipe IS_A pipe_model;
D ALIASES pipe.diameter;
r IS_A distance;
r = D/2.;

The ALIASES statement differs from the ARE_THE_SAME statement in that the equivalence between the two variables is established at the same time as the new variable is named, which makes things simpler from the point of view of building up the model's instance hierarchy.
