The term data item, as used here, includes data-names, conditions (level-88 items), constants (level-78 items) and files.
To query a data item, enter its name in the
Quick Browse dialog box. Querying a data item returns the following information in the
Output window's COBOL Source Information tab:
- Number of references
- The number of references to this data item that have been located in the source.
- Usage Indication
- A letter follows the number of references, as follows:
| d
|
The data item has no references in the Procedure Division
|
| u
|
The data item is referenced in the Procedure Division, but none of these references causes modification of the item
|
| m
|
The data item has references in the Procedure Division that cause modification.
|
- Related items
- The data items related to the target data item are listed.
Additional information is returned for the following types of data item:
- Data-name:
- Size in bytes.
- Section containing the data item's definition (File, Working-Storage, Linkage, Local or Special, where Special indicates a special register).
- Level indicator for level-01 or level-77 items.
- Subscripted indicator for items subject to an OCCURS clause.
- Filename:
- Type of file.
-
Minimum and maximum record sizes.
- Level-78 item:
- Size of the item (in alphanumeric characters).
- The value of the constant (up to a maximum of 30 characters).
In addition to a simple data item query you can specify a complex data item query (to include only certain types of COBOL verb and/or a range of lines or procedures) or a qualified data item query.
