Category dependent pre-processor for batch commands

摘要

A category dependent pre-processor for categorizes each unprocessed command of a set of batch commands into one of four zone categories and processes them differentially according to the zone categories: ignoring errors while executing unprocessed commands within a first zone category; executing until encountering an error the unprocessed commands within the second zone category; not executing the unprocessed commands within the third zone category; and executing only those of the unprocessed commands identified as within a fourth zone category that have not been successfully executed within a specified time interval from a current time, thus not executing other, remaining ones of the unprocessed commands within the fourth zone category and that have been successfully executed within the specified time interval from the current time.
