This function returns the address of its instance argument. It returns the symbol FALSE on errors. The evaluation of <instance expression> must be an instance-name or instance-address of an existing instance. If <module> or * is not specified, the function searches only in the current module. If * is specified, the current module and imported modules are recursively searched. If <module> is specified, only that module is searched. The :: syntax cannot be used with the instance-name if <module> or * is specified.
