 Changes the characteristics of RDO terminal sessions.  You can
 control:

  o  The execution of RDO data manipulation statements

  o  The display format for date values

  o  The number of statements to be included in the editing buffer

  o  The language to be used for date and time input and display

  o  The line length for RDO output (limited to 512 bytes)

  o  The default directory in the data dictionary

  o  The file in which the session is recorded

  o  The character representing the radix point in output displays

  o  The display of statements from a command file

 If you have invoked a database, you have the necessary privileges to
 use the SET statement.

 Specifies whether data manipulation queries you enter in an RDO
 session are executed (SET COMMAND EXECUTE) or not executed (SET
 COMMAND NOEXECUTE).  SET COMMAND EXECUTE is the default.

Additional information available:

EXECUTENOEXECUTE

 Instructs RDO to execute the data manipulation statements you issue
 in an interactive RDO session.

 The SET COMMAND EXECUTE statement is available only in RDO.

 Instructs RDO not to execute the data manipulation statements you
 issue in an interactive RDO session.  You can use the NOEXECUTE
 option in conjunction with RDMS$DEBUG_FLAGS to examine the estimated
 cost and access strategy associated with a query.  Although the query
 will not be executed, the access strategies will still be displayed.
 See the VAX Rdb/VMS Guide to Database Maintenance and Performance for
 information on using RDMS$DEBUG_FLAGS.

 The SET COMMAND EXECUTE statement is available only in RDO.

 Specifies the output display format for date values.  The date-number
 argument corresponds to numbers in the date format logical names used
 in the VMS Run-Time Library routines.

 Example:

      RDO> SET DATE_FORMAT DATE 6

 Changes your default data dictionary to the path name you specify.

 Example:

      RDO> SET DICTIONARY 'DISK1:[DICTIONARY]CORP.DEPT3'

 Controls the size of the editing buffer that you create when you use
 the EDIT statement with a wildcard as the parameter:

 SET EDIT KEEP n    Keep the previous n statements.  Default:  20.

 SET EDIT NOKEEP    Do not save previous commands as they are typed.

 SET EDIT PURGE     Continue to save commands, but purge buffer now.

 Changes the language to be used in date and time input and display.
 Valid entries for the language-name argument are the names of the
 collating sequences used by the VMS National Character Set Utility.

 Example:

      RDO> SET LANGUAGE FRENCH

 Sets the line length for RDO output.  Use this option to specify an
 alternate width when output is going to a file or alternate output
 device.  You can specify any number for n up to 512.

 You can put a pair or set of SET LINE_LENGTH statements into a nested
 FOR loop to change the line length during the loop.

 Names the default target for output.  The default file type is LIS.

 If you specify SET OUTPUT with a file name, RDO writes its output to
 a log file that you specify.  The output is also written to
 SYS$OUTPUT, which is usually the terminal.  If you do not specify a
 file name, RDO writes the output only to SYS$OUTPUT.  The log file
 contains both statements and results.  SET OUTPUT lets you check the
 results of command procedures run in batch mode.

 Example:

      RDO> SET OUTPUT DISK2:[DEPT3]PERSONNEL.LOG

 Closes the log file you named in the SET OUTPUT statement.

 Changes the output displaying the radix point to the specified
 character.  The radix point is the symbol that separates units from
 decimal fractions.  For example, in the number 98.6, the period is
 the radix point.

 Example:

      RDO> SET RADIX_POINT ,

 If you specify SET VERIFY, RDO displays indirect command files at
 your terminal as you run them.

 If you specify SET NOVERIFY, RDO does not display indirect command
 files.  NOVERIFY is the default setting.
