John, may be you'll get happy with pattern matching. Have you checked the java.util.regex package already? Try URL "http://java.sun.com/javase/6/docs/api/"; for example. The classes for pattern matching, also known as regular expressions, are ready to use. Well, from my experiences regular expressions are not quite common amongst MVS folks, especially REXX or CoBOL programmers. These have other well working techniques and therefor no need for regular expressions. However, also z/OS Unix has regular expressions available -- a good start for reading might be Appendix C in the z/OS Unix Command Reference.

And you are absolutely correct. So the question really is: "Once I've read a record in Java, how do I access individual fields?" So far, the best that I've seen is the Alphaworks code which can read COBOL ADATA and create Java code to access the fields. I was hoping for something "simpler", more akin to how C (struct) or COBOL (data description entries) or HLASM (DSECT) would do it. Java just doesn't seem to have anything like this. Another person mentioned "marshalling" or "serialization" which might be another approach. I need to read up on them. -- John McKown Systems Engineer IV IT Administrative Services Group HealthMarkets(r) 9151 Boulevard 26 * N.
