There are 3 other files named skip.hlp in the archive. Click here to see a list.
The SKIP command moves a magnetic tape set forward over a specified
number of files or records, or to the logical end of the tape set.
@SKIP (DEVICE) dev: n units
dev: is the name of the tape set or magnetic tape drive that
you want to move forward.
n is the number of files or records over which you want
to skip. The colon after the device name is optional.
units is either FILES or RECORDS, where records are sections
of a file; or LEOT, to skip to the logical end of the
tape set, which is the next point on the tape set
having two adjacent EOF (end-of-file) marks.
Default units - FILES
SKIP With Open Files
If you have given a CTRL/C to exit from a program that has
opened a file in a magnetic tape set and you then give the
SKIP command for that tape set, the system will first ask if
you want to close the associated file. You must do so for
SKIP to succeed, but you will probably be unable to continue
the program from that point because the file will now be
RECORDS Argument Used for Unlabeled Tapes Only
You cannot use the RECORDS argument to the SKIP command when
using a labeled tape, because read and write operations for
labeled tapes always move the tape to the beginning of a
Skipping Past LEOT (Unlabeled Tapes Only)
If you specify too large a value for n in the SKIP command
line, you can move past the logical end of tape (LEOT). In
this case, the operator may have to intervene before your
tape control commands will have effect again. You must be
sure how many files you have in the tape set if you use SKIP
n rather than SKIP LEOT. This problem can occur for any
tapes mounted on drives of the form MTAn:, or for unlabeled
tapes mounted on drives of the form MTn:.
BACKSPACE for moving a magnetic tape backward a specified number
of files or records
REWIND for returning a magnetic tape to its load point
UNLOAD for rewinding a magnetic tape completely onto the
source reel (only for tapes mounted on drives having
device names of the form MTAn:)
1. Skip over the next 2 files on the magnetic tape you are using
(mounted on magnetic tape drive MT0: in this case).
@SKIP MT0: 2 FILES
2. Skip over the next two records on an unlabeled tape.
@SKIP MTA0: 2 RECORDS
3. Use the MOUNT command to ask the operator to mount your tape
in write-enabled mode, then copy 3 files to the tape from
your directory on structure SNARK:. Use the REWIND command
to go back to the beginning, and the SKIP command to skip
over the first file. Use the COPY command to have the next
file (FIL-2) printed on your terminal, then give the SKIP
command again to skip to the logical end-of-tape. You are
skipping only one file, FIL-3, in this case.
