You should use dialog boxes for any of the following purposes:

data input	Allows for entry of file names, selection criteria, and optional parameters.
online control	Defines or restricts the online flow for the user.
data backup	Prompts users of an attempt to leave a screen without saving. This is the only way to avoid unintentional loss of data.
Confirmation or help messages	Warns the user about functions that may result in the loss of important data. This type of dialog should provide the option to cancel the operation.

Creating a Dialog Box

You create a dialog box just as you do a normal screen. However, you must remember to set the Modal dialog box attribute. You should also remember to restrict the dialog size with the Lines/columns Maint. attribute.
