ABORT

       Causes DEC DATATRIEVE to abort the remainder of a procedure or
       command file when DEC DATATRIEVE executes an ABORT statement,
       when you enter a CTRL/Z to a prompt, or when a syntax or logical
       error occurs during the execution of a command or statement.

       The exception to the logical error condition is the DELETE
       command. If you list two or more objects as arguments for the
       DELETE command, DEC DATATRIEVE does not abort if it fails to find
       an object of a specified name. Instead, DEC DATATRIEVE continues
       to delete the remaining objects in the list.

    NO ABORT

       Causes DEC DATATRIEVE, when processing a procedure or a command
       file, to abort only the one statement containing an ABORT
       statement. SET NO ABORT also causes DEC DATATRIEVE to take the
       same action when you respond with a CTRL/Z to a prompt in a
       procedure or command file. DEC DATATRIEVE then executes the next
       command or statement in the procedure or command file. SET NO
       ABORT is in effect when you start a DEC DATATRIEVE session.

    APPLICATION_KEYPAD

       Sets the keypad mode as application keypad within DEC DATATRIEVE.

       The default keypad mode for DEC DATATRIEVE is numeric keypad
       mode.

       You can also set the keypad mode using the function FN$KEYPAD_
       MODE.

       This command is not available in a DECwindows Motif environment.

    NO APPLICATION_KEYPAD

       Sets the keypad mode as numeric keypad within DEC DATATRIEVE.

       The default keypad mode for DEC DATATRIEVE is numeric keypad
       mode.

       You can also set the keypad mode using the function FN$KEYPAD_
       MODE.

       This command is not available in a DECwindows Motif environment.

    COLUMNS_PAGE = n

       Establishes the number of columns per page for DEC DATATRIEVE
       output and the default page width for the Report Writer. When you
       start your session, the default COLUMNS_PAGE setting is 80.

       To set the terminal's width, use the DEC DATATRIEVE function
       FN$WIDTH.

    DICTIONARY path-name

       Causes DEC DATATRIEVE to set your default directory node of the
       Oracle CDD/Repository data dictionary to the node specified by
       the dictionary path name. When you start your DEC DATATRIEVE
       session, your default Oracle CDD/Repository directory is
       either CDD$TOP or the directory designated by the logical name
       CDD$DEFAULT.

       SET DICTIONARY accepts both DMU and CDO style path names.

    EDIT_BACKUP

       Causes DEC DATATRIEVE to save the original definition in the
       Oracle CDD/Repository data dictionary when you use the EDIT
       command to edit a dictionary object. When you start your DEC
       DATATRIEVE session, SET EDIT_BACKUP is in effect. Use the SHOW
       EDIT command to see whether or not SET EDIT_BACKUP is currently
       in effect.

    NO EDIT_BACKUP

       Causes DEC DATATRIEVE to delete the highest version of the object
       in the Oracle CDD/Repository data dictionary, or the version you
       specify, and replace it with the definition in the edit buffer
       when you use the EDIT command to edit a dictionary object.

    FORM

       Determines whether DEC DATATRIEVE uses its forms interface when
       you use the PRINT, MODIFY, and STORE statements. For terminals
       supported by the forms product you are using, SET FORM causes
       DEC DATATRIEVE to display and use forms when you enter the PRINT,
       MODIFY, or STORE statement.

       When you start your DEC DATATRIEVE session, SET FORM is in
       effect.

    NO FORM

       Prevents DEC DATATRIEVE from using its forms interface. If SET
       NO FORM is in effect when you use the PRINT, MODIFY, or STORE
       statements, DEC DATATRIEVE does not use the forms interface.

    GRID

       Causes a client application (DEC DATATRIEVE Client for Windows or
       programs calling DEC DATATRIEVE) to display the output of a PRINT
       statement on the grid (Dataset Viewer). If the output is directed
       to a file, that file contains all the necessary tab characters
       that make it readable by other PC applications (e.g. Excel[R]).
       This command is for client applications only, and it's ignored by
       the DEC DATATRIEVE server if this is not connected to a client.

   NO CDD

   Specifies whether DEC DATATRIEVE should attach to Oracle CDD/Repository
   or use textfile-based dictionary only. When this qualifier is missing,
   the DEC DATATRIEVE behaviour depends on the equivalent string of
   the logical name DTR$ENVIRONMENT: if the equivalent string contains
   /NOCDD , no attachment to Oracle CDD/Repository occurs.
   If DTR$ENVIRONMENT is not defined, the DEC DATATRIEVE behaviour depends
   on the configuration selected at installation time.
   If Oracle CDD/Repository is linked to DEC DATATRIEVE at installation time
   its use can dynamically be disabled using the DATATRIEVE SET NO CDD
   command, which switches to the textfile-based dictionary.

    NO GRID

       Causes a client application (DEC DATATRIEVE Client for Windows or
       programs calling DEC DATATRIEVE) to display the output of a PRINT
       statement on the Output window. SET NO GRID is the default. This
       command is for client applications only, and it is ignored by the
       server if this is not connected to a client.

    GUIDE

       Starts Guide Mode, the tutorial mode of DEC DATATRIEVE. Refer to
       the DEC DATATRIEVE User's Guide for a description of Guide Mode.

    KEYDEFS file-spec

       Lets you define multiple keypad keys from a file containing
       DCL DEFINE/KEY commands (see the OpenVMS documentation for more
       information on the DEFINE/KEY command). By using SET KEYDEFS, you
       do not have to make multiple calls to the FN$DEFINE_KEY function.

       The file specification is the full DCL file specification for the
       file containing the DCL DEFINE/KEY commands.

       This command is not available in a DECwindows Motif environment.

    LOCK_WAIT

       When two applications try to access the same file, RMS may lock a
       record that DEC DATATRIEVE needs to access. DEC DATATRIEVE tries
       for 12 seconds to access a locked record. SET LOCK_WAIT causes
       DEC DATATRIEVE to turn control over to RMS after this period. RMS
       then waits for the locked record until it is released, or until
       RMS sends you a deadlock message. The default is SET NO LOCK_
       WAIT.

    NO LOCK_WAIT

       Instructs DEC DATATRIEVE not to try to access a locked record
       after 12 seconds. At the end of this period, you receive an RMS
       message informing you that the record is locked. When you begin
       your DEC DATATRIEVE session, SET NO LOCK_WAIT is in effect.

    NULLS

       When the you issue a SET NULLS command, DEC DATATRIEVE recognizes
       null values of relational databases as such. SET NULLS is the
       default.

    NO NULLS

       When you issue a SET NO NULLS command, DEC DATATRIEVE does
       not recognize null values of relational databases as such,
       it returns the type-dependent default values of relational
       databases. You can examine the current condition with the SHOW
       SET_UP command.

    PLOTS

       Establishes the default Oracle CDD/Repository DMU data dictionary
       directory for your DEC DATATRIEVE plot definitions.

    PROMPT

       Causes DEC DATATRIEVE to prompt for elements needed to complete
       the syntax of the current command or statement. When you press
       the RETURN key before completing a command or statement, DEC
       DATATRIEVE prompts you for the next syntactic element of that
       statement or command. The prompt takes the following form:

       [Looking for element]

       At the start of a DEC DATATRIEVE session, SET PROMPT is in
       effect.

    NO PROMPT

       Prevents DEC DATATRIEVE from prompting for elements needed to
       complete the syntax of the current command or statement.

    SEARCH

       Causes the DEC DATATRIEVE Context Searcher to create implicit
       inner print lists in PRINT statements and implicit ANYs in
       Boolean expressions. When you work with Oracle CODASYL DBMS
       domains, the SET SEARCH command causes the DEC DATATRIEVE Context
       Searcher to walk sets to look for a context to resolve references
       to field names.

    NO SEARCH

       Prevents the DEC DATATRIEVE Context Searcher from creating
       implicit inner print lists in PRINT statements and implicit ANYs
       in Boolean expressions. At the start of a DEC DATATRIEVE session,
       SET NO SEARCH is in effect.

    SEMICOLON

       Causes DEC DATATRIEVE to require a semicolon at the end of
       commands or statements.

    NO SEMICOLON

       Causes DEC DATATRIEVE to make semicolons at the end of commands
       or statements optional. At the start of a DEC DATATRIEVE session,
       SET NO SEMICOLON is in effect.

    VARIABLES PROCEDURES

       Allows you to use variables as procedures: you can store in a
       DEC DATATRIEVE variable commands and statements. You can then
       execute the variable as if it was a procedure. Variables declared
       as procedures are not stored in the Oracle CDD/Repository.

    NO VARIABLES PROCEDURES

       Causes variables to be interpreted as variables and not as
       procedures. At the start of your DEC DATATRIEVE session, SET
       NO VARIABLES PROCEDURES is the default.

    VERIFY

       Causes lines from command files to be displayed when a command
       file is invoked.

    NO VERIFY

       Suppresses the display of lines from command files when a command
       file is invoked. At the start of your DEC DATATRIEVE session, the
       current setting for SET VERIFY/NOVERIFY at the DCL level is in
       effect.

    HELP_PROMPT

       Causes DEC DATATRIEVE to prompt for the topic or subtopic when
       help text is displayed.

    NO HELP_PROMPT

       Suppresses the prompting for the topic or subtopic when help text
       is displayed.

    HELP_WINDOW

       Causes help text to be displayed in a scrolling region of a video
       terminal.

    NO HELP_WINDOW

       Causes help text to be displayed in a nonscrolling region of a
       video terminal.

    HELP_LINES n TO m

       Sets the lines for scrolling help text between lines n and m,
       where n represents the beginning of the scrolling region and m
       represents the end.
