The following example illustrates how you can expose a procedural program to managed applications by compiling it to JVM COBOL code with the ILSMARTLINKAGE Compiler directive. This helps expose the Linkage Section items and entry points in the procedural code to other managed languages by generating a class for each group item with the lower level data items being the members of the class.
In this example, you are going to use a slightly modified version of the calculator program which was used in the example of using wrapper classes.
