The test data may be loaded from a file via a command provided on the File menu. Test data may also be entered by typing in the input data window. By default, in order to prevent accidental changes to data entered from a file, the input data window is not editable. It may be made editable via a command provided on the File menu. If the window contains data loaded from a file, once the window is made editable, that data may be edited. On the other hand, if the user wishes to switch from data loaded from a file to data entered manually, the window may be cleared via a command on the File menu.
There is also a command to replace the test data with the contents of the result window. This is useful when sequentially refining a search.
