Extrinsic Variable exvar

exvar

Introduced in the 1990 ANSI M[UMPS] language standard.

This metalanguage symbol represents an extrinsic variable name. An extrinsic variable name looks like $$LABEL or $$LABEL^ROUTINE (no off-set allowed in this specification).

Note: An extrinsic variable is equivalent to an extrinsic function without parameters, i.e. $$LABEL^ROUTINE has the same value as $$LABEL^ROUTINE().

Modified in the 1990 ANSI M[UMPS] language standard.

An extrinsic variable may also be a reference to an external resource, i.e. $&LABEL^ROUTINE or $&PACKAGE.LABEL^ROUTINE.
