Keyword: parameter

A parameter is a value supplied by the environment before initialization.

A parameter is declared like this:

parameter p : t

where p is the parameter name and t is the type.

Parameters may be declared anywhere in the object hierarchy.

Except for the fact that it is initialized by the environment, a parameter is identical to an individual.

The manner in which parameters are supplied is dependent on the compiler. For example, if a program is compiled to an executable file, the parameter values are supplied on the command line. If it is compiled to a class in C++, parameters are supplied as arguments to the constructor.

In either case, the order of parameters is the same as their order of declaration in the program.
