The name of the component Quantity in the input card shown below is
Quantity:Record:OrderFile
When you see a colon, you can read "of". You could read the data object name for
Quantity as "The Quantity of Record of OrderFile". In the previous examples,
OrderFile is the name of the input card and the name of the type. The card name
always appears last in each object name to provide the ability to distinguish
between card objects.
Index in Map Rules
An object name can refer to a particular occurrence of a data object indicated by
the index.
For example, the third Note in a series of Note(s) has an index of 3. In a data
object name, an index appears in square brackets immediately after the type
being indexed. The indexed third Note of Report is Note[3]:Report.
Partition in Map Rules
When a type is partitioned, its subtypes - or partitions - appear in the card.
In a map rule, a partition is referenced by the symbol <> which brings to mind the
diamond-shaped icon of the partitioned type.
