Editing the Masks Table
The Masks table is a special hierarchy table that defines the hierarchy of masks. An example of a Masks table displayed in Record Mode is shown in the figure below.
The hierarchy corresponds to the tree that appears in the drop-down tree control when you choose Records ® Modify Mask from the main menu, and each record in the hierarchy corresponds to a mask that appears in the cascading hierarchy of menus when you choose Add to Mask or Remove from Mask from the Records pane context menu.

In addition to the mask name, each mask record may also contain other fields of information that further describe the mask.

Although you can view and edit the records of the Masks table in Record Mode, you should usually edit the Masks table in Hierarchy Mode, so that you can edit the mask hierarchy in addition to the other fields of each mask record.
