Many of the Peek/Spy command qualifiers may have default values supplied
   for them via logical names.

   These logical-name default values are usually defined system-wide by the
   PEEK_DEFAULTS.COM file.

   It is also possible to customize these logical-name default values in
   ones own logical name tables.

   PEEK_DEFAULTS.COM defines the logical name table search list
   LNM$PEEK_TABLE_SEARCH_LIST. This table search list specifies the
   tables which are searched for logical-name default values. These
   tables are searched in the order specified by this logical name.

   As shipped, PEEK_DEFAULTS.COM defines LNM$PEEK_TABLE_SEARCH_LIST to
   search the LNM$PROCESS, LNM$JOB and LNM$GROUP logical name tables,
   in that order, before checking for a system-wide default value in
   the table LNM$PEEK_DEFAULT.

   See the PEEK_DEFAULTS.COM file for more information.
