bits in all states to be ignored in the comparison. The compare data

image itself remains unchanged on the display. The Mask fields are

directly above the label and base fields at the top of both the Compare

and Difference listings (see fgurel2-2). When you select one of these

fields a pop-up appears in which you specify which channels are to be

compared and which channels are to be masked. A "." (period)

indicates a don't compare mask for that channel and an "*" (asterisk)

indicates that channel is to be compared.
