User Defined Function

With the introduction of z/OS COBOL 6.4, user-defined functions (UDF) is a noteworthy addition to the COBOL framework. UDF provide the capability to define custom functions using the FUNCTION keyword and can be invoked statically, dynamically, or via a dynamic-link library (DLL). While careful considerations are needed for structuring and invoking these functions, stay tuned as T-Rexy plans to provide sample code in the future, offering practical insights into their implementation.
