Displaying Executed Commands
To display commands that were recently executed in the Neoview Script session, enter the
HISTORY command. The HISTORY command associates each command with a number that
you can use to reexecute or edit the command with the FC command. See “Editing and
Reexecuting a Command” (page 58).
For example, this HISTORY command displays a maximum of 100 commands that were entered
in the session:
SQL>history
1> set idletimeout 0
2> set schema persnl;
3> select * from project;
SQL>
To save the session history in a user-specified file, enter the SAVEHIST command. For example,
this SAVEHIST command saves the session history in a file named history.txt in the local
directory where you are running Neoview Script:
SQL>savehist history.txt
For more information, see the “HISTORY Command” (page 90) and the “SAVEHIST Command”
(page 101).
Editing and Reexecuting a Command
To edit and reexecute a command in the history buffer of a Neoview Script session, enter the FC
command. To display the commands in the history buffer, use the HISTORY command. See
“Displaying Executed Commands” (page 58).
For example, this FC command and its delete (D) editing command correct a SELECT statement
that was entered incorrectly:
SQL>fc
SQL>selecct * from employee;
.... d
SQL>select * from employee;
....
Pressing Enter executes the corrected SELECT statement.
For more information, see the “FC Command” (page 87).
Clearing the Interface Window
After entering commands in the Neoview Script interface, you can clear the interface window
by using the CLEAR command. For example, this CLEAR command clears the interface window
so that only the prompt appears at the top of the window:
SQL>clear
For more information, see the “CLEAR Command” (page 83).
Obtaining Help
To display help text for an interface command that is supported in the current operating mode
of Neoview Script, enter the HELP command. For example, this HELP command displays syntax
and examples of the FC command:
SQL>help fc
For more information, see the “HELP Command” (page 90).
