5.17 HETMAP (Show information about a HET or AWS tape file)

5.17.1 Function

The Hercules HETMAP program displays information about a HET or an AWSTAPE tape file. By default,
HETMAP shows label and file information. Optionally, HETMAP may be used to display data set infor-
mation, or to display label information in a format similar to the output of TAPEMAP. HETMAP shows
information about the tape and files on it, and does not display actual file contents.
