ViewPoint console application. An extensible interactive application for operators. It
allows a system or a network to be controlled from a single terminal. It includes several

status, a conversational TACL screen, and a facility called Define Process to maintain
sessions with multiple subsystems at the same time.
warning. A condition, encountered in performing a command or other operation, that can be
significant but does not cause the command or operation to fail. A warning is less
serious than an error. See also error.

compare operations to mask characters that are not significant. The NetBatch wild-
card characters are * (asterisk) and ? (question mark).
