ALCS goes one step further.  Message fields are tagged to make parsing even 
easier, eg:
DXC081E DB2 CAF entry point load failed- Abend code AC-X'abend_code'Reason code 
RSC-X'reason_code'
Best wishes / Mejores deseos /  Meilleurs vœux

As I said before, MVS automation doesn't need regexp. It has message ids that 
make simple *abc* pattern matching sufficient. MVS has message IDs with well 
defined messages. Look at any product messages manual. Look at messages in 
Quikref. 


MVS automation gives you direct access to fields. With non-MVS automation 
potentially dealing with thousands of products, do you think they usually deal 
with fields or do you think they are dealing with a single message.
