Unibase by DMAC, Release 8.4.37 or later, now has an Environment option, UBNRKD, which will delete any batch that is terminated or interrupted in data entry or image entry and the batch has no records.
A DMAC client pointed out that in their environment they used wild cards to output data and did not wish an empty batch to even be recorded in the output run. In addition, they said that first the wrong keyer started a batch and then recognized that it was the wrong batch and closed it before any keystrokes. Then the keyer who needs to reference the batch would find it already existed and would be confused.
This environment variable solves such problems. The UBNRKD environment variable joins hundreds of other environment variables which enable Unibase clients to customize the Unibase environment to their liking.
