Generating no output

Each map rule cell requires a map rule. If an output is optional, you may not want to generate the output for that data object. 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. The word NONE is case-sensitive.

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.
