Problem:
This demo returns information about the operating system environment via the library call CBL_GET_OS_INFO. This demo also demonstrate the usage of the Library Routine Type definitions and Call Prototypes. Net Express contains two copyfiles; one contains data items used by the library routines specified as type definitions, or TYPEDEFs, while the other contains call prototypes for the library routines. These can be used in your COBOL programs to enable the Compiler to validate all calls to these routines.
Resolution:
