The following example displays the default settings and change
       the default settings with one SET statement:

       DTR> SHOW SET_UP
       Set-up:
           Columns_page: 80
           No abort
           Prompt
           No search
           Form
           No verify
           No semicolon
           No lock_wait
           NULLs support
           Application keypad mode

       DTR>  SET COLUMNS_PAGE = 132, ABORT, NO PROMPT, SEARCH,
       [Looking for SET option]
       CON> 9 NO FORM, VERIFY, SEMICOLON, LOCK_WAIT, NO APPLICATION_KEYPAD

       DTR>SHOW SET_UP
       Set-up:
           Columns_page: 132
           Abort
           No prompt
           Search
           No form
           Verify
           Semicolon
           Lock_wait
           NULLs support
           Numeric keypad mode

       The following example sets your default dictionary directory at
       CDD$TOP and uses a variety of path names to change your default
       directory:

       DTR>  SET DICTIONARY CDD$TOP
       DTR>  SET DICTIONARY DTR$LIB.DEMO
       DTR>  SHOW DICTIONARY
       The default directory is CDD$TOP.DTR$LIB.DEMO
       DTR>  SHOW DICTIONARIES
       Dictionaries:
       DTR>  SET DICTIONARY -.-;
       DTR>  SHOW DICTIONARY
       The default directory is CDD$TOP
       DTR>  SET DICTIONARY CDD$TOP.DTR32
       Element "CDD$TOP.DTR32.JONES" not found in dictionary.
       DTR>  SET DICTIONARY CDD$TOP.DTR32.TEST
       DTR>  SHOW DICTIONARIES
       Dictionaries:
       DTR>  SET DEF -; SHOW DICTIONARY
       The default directory is CDD$TOP.DTR32
       DTR>  SHOW DICTIONARIES
       Dictionaries:
               AWS             BRADS           BRENT           DBF
               DDD             DEMO            DENN            DETRIC
               DUNCAN          JAS             KELLERMAN       LANDAU
               MARISON         PLOTS           STRONG          TEST
               WAYNE

       DTR>  SET DICTIONARY WAYNE
       DTR>  SET DICTIONARY DISK1:[SWANSON.DTRWORK]TEST.NEWDICT
       DTR>

       The following example uses the SET SEARCH command to walk sets in
       a Oracle CODASYL DBMS database:

       DTR>  READY SUPPLIES, VENDORS, PART_S
       DTR>  SET SEARCH
       DTR>  PRINT VEND_NAME, PART_DESC OF
       [Looking for name of domain, collection, or list]
       CON>     VENDORS WITH VEND_NAME = "QUALITY COMPS"
       Not enough context. Some field names resolved by Context Searcher.
       --------------Vendor Name---------------

       QUALITY COMPS
       VT100 KEYBOARD ASSY
       NUMERIC KEYPAD FRAME
       VT52 HOUSING

       When SET SEARCH is not in effect, you need to provide explicitly
       the inner print lists to give DEC DATATRIEVE the necessary
       context, as follows:

       DTR>  SET NO SEARCH
       DTR>  PRINT VEND_NAME, ALL ALL PART_DESC OF PART_S OWNER OF
       [Looking for set name]
       CON>     PART_INFO OF SUPPLIES MEMBER OF VENDOR_SUPPLY OF
       [Looking for name of domain, collection, or list]
       CON>     VENDORS WITH VEND_NAME = "QUALITY COMPS"
       --------------Vendor Name---------------

       QUALITY COMPS
       VT100 KEYBOARD ASSY
       NUMERIC KEYPAD FRAME
       VT52 HOUSING
