Card Specifics
♦ More than one card in a map can reference the same type but the cards must
have different card names.
♦ Each card is assigned a number when it is created. Cards are numbered
sequentially, beginning at 1. The card numbers determine the order in which
the cards and the data in those cards is evaluated. The card number is
important when a map is used as a functional map. To reorder the cards, use
the Reorder command on the Card menu.
♦ The structure of the card object appears in the card. An icon represents each
component that the entire card data object is composed of. Each icon in the
input and output card represents a type that has been defined in the Type
Designer.
! Icons that display a plus sign (+) may be expanded. Click the plus sign to
show its components or partitions.
! Icons that display a minus sign (-) may be contracted. Click the minus sign
to hide its components or partitions.
♦ The output column in the output card shows the structure and the names of
the components of the output data object.
♦ In the case of partitioned groups, the structure shown is the partitioned group
and its subtypes. An icon is shown for each component and each partition that
compose the entire card object.
♦ Each output name appears in a separate cell in the output card.
♦ The rule column contains a rule cell for each output object. Enter map rules to
define how to generate the data object of this card.
♦ There are several ways to view input and output cards.
Viewing Input and Output Cards
Maps contain one or more cards. There are three ways to display the input and
output cards in the Map Designer window.
To display a card
