Yes, it works in practice (especially since a failed DBUPDATE does not require a DBXUNDO as of MPE/iX 5.0). That said, do you have NetBase? A programmer here tried a program with dynamic rollback against a NetBase'd database, and promptly caused a system abort. He wasn't sure it was his program :( so he ran it again when the system was back up. He discovered it was indeed his application. That was under MPE/iX 4.0; I don't know which version of NetBase. --Glenn Cole Software al dente, Inc. [log in to unmask]
