Scripting Languages and COBOL
Comments (2) The use of scripting languages with other languages has increased over the last couple of years, from a simple case of interoperability, reuse of scripting code to allowing your code to customised via the user of external scripts. All of which are real world examples I have seen customers use.
Interoperability between languages is very important to COBOL environments just as much as other languages. Some platforms such as Microsoft’s .Net with their CLR makes life much easier by allowing all languages to share a common infrastructure ie: the instruction set and the VM (MSIL and CLR) along with a base class library to get you started.
Environments such as Sun’s VM (JVM) provide two different approaches to interoperability with Java, the first is via JNI/JNA and the second is producing bytecode that runs as is on the VM.
Although the Micro Focus COBOL compiler does not support JVM bytecode or Java source generation it does have support for invoking classes/methods via the OO invoke verb.
