Generating no output

Each map rule cell requires a map rule. For map rules for data objects for which you do not want to generate output, enter the following:

= NONE

The reserved word NONE specifies to generate none of the given output.

You don't have to type in the rule = NONE. The command Insert NONE if Empty puts this rule into the empty rule cells on the active output card, including those empty cells that cannot be seen by the current view of the card.

To insert = NONE in every empty rule cell:

1. On the Rules menu, click Insert NONE if Empty.

   Only empty rule cells that are showing when you scroll up and down in the output card will be filled. To enter = NONE in all empty cells, including the ones that are nested beneath unavailable cells, use the Show All command on the Rules menu and then choose Insert NONE if Empty.
