Eclipse project - TwoPackageSet

The Eclipse project we provide for this tutorial contains the TwoPackageSet project, which is a native COBOL project.

The project also contains the TwoPackageSet.cbl program, which is a COBOL SQL program that switches between the PROD and TEST package sets.

The demonstration Eclipse project and its components are located in the %PUBLIC%\Documents\Micro Focus\Enterprise Developer\Samples\Mainframe\SQL\hcoss\TwoPackageSet directory by default.
