What is extensibility, and why is it important?
Extensibility mechanisms allow you to build new features out of old ones. While any language which has objects, macros, and subroutines possesses a degree of extensibility, the mechanisms in SLX go well beyond those found in other languages. For example, SLX has a statement-definition facility with which you can add new statements to the language. This enables you to develop a dialect of SLX which is custom-tailored for your application. For example, if your models frequently deal with conveyors, writing them using verbs such as “place on” and “remove from” is much easier than using general-purpose simulation verbs. Back to top.
