Displaying Executed Commands

For more information, see the “SHOW SYNONYMS Command” (page 124).

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).
