named argument

Key "a" has a dictionary value containing named arguments to the query.

Keywords are usually used to label named arguments to functions, and to represent symbolic values.

Named arguments are grouped in the Named collection object and have the usual methods like Item, Count, Length as well as an Exists method.

Within the function, the arguments may also be accessed through the object; this provides access to all arguments using indices (e.g. ), including those beyond the number of named arguments.

Subroutines may assign to a hash to simulate named arguments; this is recommended in Perl Best Practices for subroutines that are likely to ever have more than three parameters.

Note that CAL allows multiple constructor arguments to be cited in a case extractor, along with multiple constructors to match on (so long as they all have the named arguments).

The Basic Logic Dialect (BLD) adds features to the Core dialect that are not directly available such as: logic functions, equality in the then-part and named arguments.

WSH 5.6 introduces named arguments on the command line which follow a /string:value or boolean convention defined in 'Runtime' tag and are recognized irrespective of their order on the command line.

This version is slightly different from the Research Unix version, with the most notable difference being that numbered function arguments ($1, $2, etc., as in the Unix shell) were replaced by named arguments (as in C).

The number of arguments given when calling a function may not necessarily correspond to the number of arguments in the function definition; a named argument in the definition that does not have a matching argument in the call will have the value (which can be implicitly cast to false).
