Demonstration Programs

Your COBOL development system includes some demonstration programs that illustrate different aspects of calling procedural COBOL from Java. These demonstration programs are contained in the $COBDIR/demo/javademo/cobol directory in your product installation. Each directory includes all relevant program files, as well as a readme.txt file to explain the programs in more detail.

The following table shows the directories containing the demonstration programs and gives a brief description of the purpose of the demonstration:

Directory	Illustrates
arrays	Reading a Java array from COBOL. Updating a Java array from COBOL.
pi	Calculating pi. Passing numbers back to Java via Strings.
primtypes	Passing primitive Java types to COBOL. Updating primitive Java types from COBOL.
record	Writing a simple COBOL Java object. Receiving structures in a COBOL program from Java objects that implement the DataType interface. Passing parameters by reference.
