The Interface Configuration page controls the History Size. The History Size option specifies how many sets of previous commands, called scripts, are saved in an internal buffer for possible reexecution later. This page also allows you to adjust, in the Input Area Size section, how big a window you need to enter your SQL statements.
You can also specify in the Output Location section how the output from the SQL statements will be displayed: below the input area or saved to an operating system file in HTML format. Finally, the Output Page Setup lets you control whether the output from the script appears on a single page or on multiple pages. If the output appears on multiple pages, you can also specify how many lines to display per page.
Executing a script and formatting its output are controlled by system variables. Like a column in a row of a table, a system variable can hold a string or a number.
Any characters beyond this limit will wrap to the next line. Turning the column headings off may be useful, for example, when sending the output of a SQL query to a file for processing by another program that may not need to have the column headings. A single character, which is the vertical bar by default, divides the heading onto multiple lines. The Change Password page allows you to change your Oracle login password.
