Conditional Compilation: How to use @if blocks


I am having trouble using the conditional compilation @define,@if,@elseif,@else,@end.

My question is: where can I use this conditional compilation?

Because I have a model with many “options”: for example, I would like to choose between a model without price-stickiness and one with price-stickiness. The difference between them is a couple of equations and new variables. I would like to have them both written in the same *.mod file. I thougth that using a @if block would help me: something like
@define version 1;

@if version == 1;
equations with price stickiness…
equations without price stickiness…

I couldn’t do that. Is this possible? Which is the correct use for the @if block?


Conditional compilation isn’t available yet in version 4.
