To help reduce data structure duplication across your COBOL applications you can extract a block of COBOL code to a copybook.
To extract the code, perform the following steps:
- In the COBOL editor, highlight the lines that you want to extract to a copybook.
- Right-click in the COBOL editor, and then click
. Alternatively, from the main menu, click
This opens the
Extract to Copybook dialog box where
Containing project contains the current project.
- In the
New file name field, type a copybook file name with either a
.cbl file extension.
- Optionally, click
Preview to view the changes to be performed. In the
Changes to be performed pane, you are presented with a list of the actions to be taken. By default, all actions are checked. You can uncheck actions
to obtain the required results. Clicking on the actions displays the result of the actions in the
Original Source and
Refactored Source panes.
By default this extracts the highlighted source code to the specified copybook and refactors the original source, leaving
a COPY statement referencing the newly-created copybook.
