TAPE TAPE Use the TAPE command to dump CMS'-formatted files from disk to tape, load
previously dumped files from tape to disk, and perform various control
operations on a specified tape drivee Files processea by the TAPE
command must be in a unique format. The TAPE command does not
process multivolume files. Disk files to be dumped can contain either
fixed- or variable-length records. The format of the TAPE command is:

specified, only that one file is loaded. If the option EOP n
is specified and no file identifier is entered, n tape files
are written to disk. If an asterisk (*) is specified for fn

identifier are loaded.

positions the tape at a specified point, and lists the
identifiers of the files it scans. Scanning occurs over n
tape marks, as specified by the option EOP n (the default is 1
tape file). However, if a file identifier (fn and ft) is
specified, scanning stops upon encountering that file; the
tape remains positioned ahead of the file. positions the tape at a specified point and lists the
identifiers of the files it skips. Skipping occurs over n
tape marks, as specified by the option EOP n (tme default is 1
tape mark). However, if a file identifier (fn and ft) is
specified, skipping stops after encountering that file; the
tape remains positioned immediately following the file. MODESET sets the values specified by the DEN, TRACK, and TRTCH
options. After initial specification in a TAPE command, these
values remain in effect for the virtual tape device until they
are changed in a subsequent TAPE command or RDTAPE, WRTAPE, or TAPECTL macro.
