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.

DEN den is the tape density where den is 200, 556, 800,. 1600 r or 6250. If 200 or 556 is specifiedr 7TRACK is assumed. If 1600 or 6250 is specified, 9TRACK is assumed; if 800 is
specified, 9TRACK is assumed unless 7TRACK is specified. In
the case of either 800/1600 or 1600/6250 dual-density drives r 1600 is the default if the 9TRACK option is specified. If
