Mapping from a Floating Component Type
If an input card data object is a group that has a floating component type, you can
map from the floating component type. A floating component must be
distinguishable from every component of the group it is assigned to. On input, a
floating component can appear after the initiator and after each component. If a
floating component is associated with an input data object, it can appear as the
first component.
If a type object has content, a floating component is built as the specified literal
after the initiator and after each component. If this feature is used, it is up to the
user to include a literal that will validate as an object of the type of the floating
component.
Note You cannot map to a floating component in the output. If you have a floating
component in the output data to which you want to map, you must define them as
components of the output.
To display floating component types on the input card
1 From the Tools menu, choose Options.
2 Click From Window.
3 Enable the Show floating component type check box.
4 Click OK.
To map from a floating component type in an input card object, drag the floating
component type into the rule cell of the output object on the output card. To map
from a nested component of that floating component, drag the nested component.
Mapping From a Floating Component of a Particular
Component
You can map from a floating component that appears after a particular component
of the input card object.
To refer to a floating component after a particular component
1 Select the component whose floating component you want to map.
2 Drag the floating component, or a nested component of the comment, into the
output object rule cell.
