Built-in_Rules

   MMS uses built-in rules when you omit the action line or the  source,
   or  both, from a dependency rule.  Built-in rules allow MMS to assume
   dependencies that are not stated  in  the  description  file  and  to
   perform  actions  necessary  to  update  the target.  To decide which
   built-in rule to apply to a dependency, MMS also  uses  the  suffixes
   precedence list.

   Built-in rules also allow you to  access  files  stored  in  OpenVMS,
   CMS,  FMS libraries and records stored in the Common Data Dictionary.
