Special Characters in Map Rules
To enter a Hexadecimal value of a special character in a map rule, enter the Hex
value for the characters in double brackets (open and close carets).
For example, to enter the text value <WSP>, enter the Hex value for the open caret
<<3C>>, and then the literal values for the rest: WSP>
<<3C>>WSP>
Referencing an Output in a Map Rule
To enter the object name of an output data object, drag it to the Rule Bar just as
you do with an input data object. Output data is built from top to bottom,
beginning at the first output card.
You can map an output to another output, as long as the output you are mapping
from is evaluated before the output you are mapping to.
You can reference an output in the same card or another card. Referencing a data
object from another output card, as long as that output card is evaluated before
the output card containing the map rule.
To reference an output in an earlier output card
1 To show two views of the output card, drag any card from the To window to
the main window.
2 View and select the destination rule cell where you want to enter the object
name into the map rule.
3 In the other view of the To window, view the output card that contains the
data object you want to enter.
4 Drag the object into the destination rule bar.
Comments in Map Rules
You can add inline comments to map rules. Comments do not affect how map
rules are evaluated. A comment may appear anywhere in a rule, as long as it does
not separate object names.
A comment is identified with the start characters /*. While the end characters */
can be present, they are not required. If the end characters are not present,
everything up to the end of that rule is the comment.
