DEC DATATRIEVE is a data management tool for defining,
   storing, updating, and displaying data. It provides
   interactive and program-callable access to data, a report
   writing facility, a graphics capability, screen formatting
   support, and distributed access on a network connected by
   DECnet. To invoke the default DEC DATATRIEVE image enter:

 	$ DATATRIEVE

   Enter:

 	$ DATATRIEVE/VARIANT=xx

   to invoke other DEC DATATRIEVE images that are installed on
   your system, where xx is the suffix appended to the image
   name. See the "DCL-command" help subtopic for additional
   information on the DATATRIEVE DCL command.

1  –  Release Notes

   Release notes for DEC DATATRIEVE are contained in the
   file:

 	$ SYS$HELP:DTR*.RELEASE_NOTES

   You can type or print this file to read the release note
   information.

2  –  UETP

   DEC DATATRIEVE User Environment Test Packages (UETPs) have
   been provided and can be run after the installation is
   complete. They are invoked from DEC DATATRIEVE as follows:

     DTR> @sys$common:[systest.dtr]dtr     ! General test
     DTR> @sys$common:[systest.dtr]plots   ! Plots test
     DTR> @sys$common:[systest.dtr]dbms    ! DBMS test
     DTR> @sys$common:[systest.dtr]rdb     ! Rdb test
     DTR> @sys$common:[systest.dtr]forms   ! Forms test

3  –  DCL command

   You can invoke DEC DATATRIEVE from DCL command level with the
   DATATRIEVE DCL command. The DCL DATATRIEVE command lets
   you specify options to customize your DEC DATATRIEVE session.

   You can abbreviate the DCL DATATRIEVE command to the
   shortest form that is unique among other DCL commands.

   The DATATRIEVE command has the following format:

     DATATRIEVE  [qualifier [...]]  ["dtr-command-string"]

3.1  –  Qualifiers

   The optional qualifiers to the DATATRIEVE command include
   the following:

   /INTERFACE

 	/INTERFACE = {DECWINDOWS}
 		     {CHARACTER_CELL}

   Specifies the display interface to be used by DEC DATATRIEVE.
   If your default environment is the command-line
   interface, then CHARACTER_CELL is the default. If your
   system is properly defined to invoke the DEC DATATRIEVE
   interface to DECwindows Motif, the default is DECWINDOWS. This
   qualifier overrides the setting specified by the
   DTR$NOWINDOWS logical.

   /DEBUG

 	/[NO]DEBUG

   Specifies whether DEC DATATRIEVE should display special debug
   messages. The default is NODEBUG.

   /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 .

   /VARIANT

 	/VARIANT = image-suffix

   Indicates the 1- to 26- character suffix applied to a
   DEC DATATRIEVE image upon installation to uniquely identify
   that image. This qualifier is needed only if you invoke
   a DEC DATATRIEVE image that was not selected as the default
   image at installation time. The DATATRIEVE command in the
   following example invokes DTR32FMS.EXE:

   $ DATATRIEVE/VARIANT=FMS

   If you want to run DTR32.EXE, and it is not the default
   image on your system, use the /VARIANT qualifier alone, as
   in the following example:

   $ DATATRIEVE/VARIANT

3.2  –  dtr_command_string

   The DCL DATATRIEVE command can take a DATATRIEVE command
   or statement as an argument. This allows you to execute a
   DATATRIEVE command, statement, or procedure without
   entering interactive DEC DATATRIEVE. If the
   dtr-command-string contains more than one word, it must be
   placed in quotation marks.

   For example, to invoke the DEC DATATRIEVE procedure REPORT
   which is located in CDD$TOP.JOB, you would enter

     DATATRIEVE "EXECUTE CDD$TOP.JOB.REPORT"

4  –  Motif Interface

   DECwindows Motif provides DEC DATATRIEVE users with an easy way
   to execute command procedures, to open and close log
   sessions, to navigate through and set dictionaries, to
   set other DEC DATATRIEVE setup parameters, and to display
   information on certain DEC DATATRIEVE sources.

   To invoke DEC DATATRIEVE with the DECwindows Motif interface, use
   the following command:

           $ DATATRIEVE/INTERFACE=DECWINDOWS

   This qualifier overrides the setting specified by the
   DTR$NOWINDOWS logical.

5  –  Client for Windows

   DEC DATATRIEVE Client for Windows is a Windows application
   which provides a user-friendly graphical interface, on
   Personal Computers running Microsoft Windows, for performing
   DEC DATATRIEVE operations on a connected server.

   DEC DATATRIEVE Client for Windows is layered on and requires
   the DEC DATATRIEVE Version 7.0 or later software which contains the
   Extended Client-Server API and takes care of the client-server
   connection and communications.
