Description
A parameter
identifies something passed from
one part of a computer system to another. In this regard
parameter
is fairly generic, but it may have a more
constrained semantic in some contexts (e.g., in a
paramdef
).
In a document that describes more than one kind of parameter—for
example, parameters to functions and commands—the class
attribute can be used to distinguish
between them, if necessary.
Processing expectations
Formatted inline.
Attributes

- class

Enumerated values: “command” A command
