How do I  access a java program to convert a date?

The existing COBOL programs CALL with the following syntax:

CALL 'JULGREG' USING WD-JULIAN-DATE WD-GREGORIAN-DATE.

The Julian date is received and converted to a Gregorian date which is needed in our application. What is the recommended method for accomplishing this "by reference" or is there a default?

Answer:

CALL BY REFERENCE is default, so var.fromText("...") from the Java side.   Or it can be returned as the value of the call() method from Java, and use RETURNING MY-VAR on the Cobol side.

Please check the the extra built-in intrinsic date functions, they may already satisfy your requirements.
