The ampersand (&) character designates a program whose namespace is external to the current M environment. The effects of passing parameters are as defined in 8.1.7 (Parameter Passing).
The packagename shall be from a namespace of those determined by the appropriate namespace registry. If packagename is not specified, implementors may, optionally, choose to provide a default package.
Bindings may have one or more namespaces; requirements to use these namespaces must be clearly stated in the specification of the binding. The term package is used herein to denote programs that are in possibly external environments. No implied one-to-one correspondence for all possible external packages exists.
The externalroutinename namespace is not defined in this document; this is a function of a binding. Any external mapping between the externalroutinename and any name used by an external package is an implementation-specific issue. The externalroutinename shall be of the form name or name1^name2.
