FORWARD MODULE module-name [<argument-list>] [<default-list>]
------------------------------------------------------------------------

.b 3
The FORWARD MODULE macro specifies that ^&module-name\& is a module that is not
yet defined. Therefore, you can reference this module before it is defined
later in your program. It also specifies that _<^&argument-list\&_> are the
required arguments for the module. 
.b
If no arguements are specified in _<^&arguement-list\&_>, no arguments are
passed to the module and _<_> must be specified as a place holder for
the _<^&argument-list\&_>.
.b
If _<^&default-list\&_> is specified, each element in the _<^&argument-list\&_>
must be present in the _<^&default-list\&_>, plus each element in the
_<^&default-list\&_> may be set to a default value.
