The Alias &1 is used as a menu service. This Alias does not identify an entry in the Alias table.
&1 - The Alias ID read from the template.
The alias &1 has been used in a template (in a /(MENU-...) replacement marker) - but no entries with this identification exists in the Alias table.
Another possibility is that the alias has been specified for the WSLOAD parameter on an external link. If this is the case, a message with the type EvF149 will be written to the file after this one.
Either change the alias in the template or change/create the alias in the alias table to correspond to the alias specified in the template.
If the alias has been specified on an external link, no action is necessary.
