Create the wrapper project

The BookWrapper.cbl interface has a similar interface to Book.cbl but updated to turn the file status into a string and a numeric value, and pass it back in lnk-status-group. The setup-status section does the conversion. 

procedure division using by value lnk-function by reference lnk-b-details lnk-status-group.

The BookWrapper.cbl program is compiled with the ILSMARTLINKAGE directive which creates classes to represent the PROCEDURE DIVISION parameters. In the bin folder will be Details.class and StatusGroup.class. This will be seen in action in the creation of the bridge code between the server code and the COBOL application.
