PERCobol supports direct creation of Java classes, with Java capabilities. (This is not yet standard Cobol 200x standard, but rather closer to it with a Java capabilities. So single-inheritance and multiple implementation is available, exactly as in straight Java.)

CLASS-ID. name INHERITS "class" IMPLEMENTS "class" ... .
METHOD-ID. name.
DATA ...
PROCEDURE...
END METHOD.

METHOD-ID. name.
END METHOD.

METHOD-ID. name.
END METHOD.
...
END CLASS.

In PERCobol, each program and class may be instantiated multiple separate times. (A separate working-storage is created, for example.)

Object references and INVOKE's are supported in PERCobol. An empty method name in the INVOKE is the constructor.
