Chapter 7 - Formulating Map Rules
This chapter provides information on implementing map rules to build the desired
output results.
Generating No Output
If an output is optional, you may not want to generate the output for that data
object. In situations in which you do not want to generate output for a data object
on an output card, enter a special rule. The rule for generating none of an output
is simply:
= NONE
Note The word NONE is case-sensitive.
This data object will
generate no output
Text Literals As None
The use of “” as text literals in a map rule evaluates to NONE. For example, the
following two rules are equivalent:
= EXTRACT (Record:Input, Store:Record:Input = "")
= EXTRACT (Record:Input, Store:Record:Input = NONE)
