The ID.ONLY keyword causes the query processor to ignore the default listing phrase and show only record ids. The synonym ONLY may be used.
Used with no field names on the command line, the ID.ONLY keyword causes the query processor to ignore the default listing phrase (@ or @LPTR) and to show the record its only. If field names are given on the command line this keyword has no effect.
For compatibility with other multivalue products, the ID.ONLY keyword may appear before the file name in a query processor sentence. For example:
