The FD form shows the logical structure of the data items and some of the augmentations that you have applied to the items,
but to view more detail about a particular item, you need to refer to the Properties pane displayed on the right-hand side
of the FD form. For each item is shows the following information:
Data Items
The following properties are displayed for typical data items in the FD:
File Item Info

- The name of the COBOL data item specified in the imported FD.
- Picture
- The value of the Picture clause.
Note: For group level items, it will indicate "Group [X(nn)]", which may not match exactly with what the original imported FD specified, as
Designer creates its own representation: for example, 999 might instead be represented as 9(3).
- Offset

- Length
- The length, in bytes, of the data item.
- Occurs
- Indicates the occurs value of the data item, such as
<min>/<max>, or Depending On
<data-item>
- Subscript Count
- The number of subscripts (or COBOL indices) required to reference this item in COBOL.
- Subscript Name
- The name of the synthetic item that serves as a subscript if the item is in an OCCURS clause.
- Redefines
- Specifies the data item this data item redefines.
- Redefined By
- Specifies the data item that redefine this one. If there are multiple redefines of this item, only one will be displayed.

and have this value set to
False.
Advanced
- Null Value
- See
Defining Null Information.
- Redundancy Set
- Identifies any redundancy sets: see
Defining Item Sets.
Conditional (88-level) Data Items
The following properties are displayed for 88-level items in the FD:
- Value
- Represents the Value that results in a true condition. Also, it is the value that it is set to if the Condition is set to
True.
- True Value
- Represents the values that results in a true condition.
- False Value
- Represents the values that results in a false condition.
Subscripted Data Items
The following properties are displayed for subscripted items in the FD:
- Table Name
- Identifies the table that the subscripted data item is associated with.
