There are 17 other files named direct.hlp in the archive. Click here to see a list.
DIRECT is a program to provide a directory listing of files from a
file-structured device such as disk or DECtapes or from magtapes
written by FAILSAFE, FRS, BACKUP, or DUMPER (TOPS-20). The command
format is "listing-file=file1, file2, . . . " where listing-file is
the file specification of where the directory listing is to go
(default is to the job's controlling terminal) and file1, file2, etc.
are the files to be listed (default device is DSK:, default file name
and type (extension) are *, default directory is controlling job's
default path).
DIRECT switches (to control output listing format) are:
/ACCESS:n Do an accessing LOOKUP (one which will cause the
file's access date to be updated) of any file
whose length is "n" blocks or less. Normally
DIRECT will not cause the file's access date to be
changed.
/[NO]ACCOUNT Do [not] list the file's account string. Default
is /NOACCOUNT.
/ALLOCATED When listing the file's length use the file's true
physically allocated length rather than the
written data length. Default is /WRITTEN.
/[NO]AUTHOR Do [not] list the file's author if the author is
different from the owner. Default is /NOAUTHOR.
/BLOCKINGFACTOR:n Set the number of disk blocks per tape block read
from tape. The default value is 4 for
compatibility with tapes written by BACKUP without
blocking factor capability. The specified value
must be in the range of 4 to 96, and be a multiple
of 4 disk blocks. Due to KS10 UNIBUS adapter
limitations, the maximum blocking factor on a KS10
is 56.
/[NO]CHECKSUM Do [not] compute and list the file's checksum.
Default is /NOCHECKSUM.
/[NO]COMPARE Suppress directory listing headers and titles as
well as error messages so that the directory
listing may be compared (using, for example,
FILCOM) to another directory listing. Default is
/NOCOMPARE.
/[NO]DETAIL Do [not] provide a detailed listing of all known
file attributes (such as block number of the RIB,
etc.). Default is /NODETAIL.
/[NO]DIRECT Do [not] provide an ASCII directory listing.
Default is /DIRECT.
/DTA List in old DECtape format.
/[NO]EOTS When reading a magtape, do [not] stop reading the
tape at logical end of tape (two consecutive end
of file marks). Default is /EOTS.
/[NO]ERLOG Do [not] enable automatic device error logging.
Default is /ERLOG.
/FAST Provide a fast directory listing consisting of
only file name and type (extension) information.
This avoids having to LOOKUP each file for such
information as the file's length, creation
date/time, etc. Certain switches such as
/CHECKSUM will force a LOOKUP anyway. Default is
/NORMAL.
/FILES:n When reading a magtape stop after "n" physical
files (end of file marks) have been read.
Normally DIRECT reads until end of tape (see
/EOTS) is encountered.
/[NO]FIND Do [not] use the "find files" rather than the
actual physical device(s) specified in order to
provide the directory listing. Default is
/NOFIND.
/[NO]FLSDIR Do [not] print the file's device and directory on
the right hand side of the first line of the
directory listing for each different directory
listed. Default is /FLSDIR unless either /HDSDIR
or /WIDTH is specified.
/[NO]FNDBLD Do [not] generate "find files" containing the
directory information. If /FNDBLD is specified
the "find files" are generated from the output
file specification with extensions .FDF and .FPF.
Defaults are device DSK:, filename(s) FNDDAT,
directory [-]. The "find files" may be later read
by the /FIND switch. Default is /NOFNDBLD.
/FNDDAT:file When /FIND is specified, use "file" as the file
specification of the "find files" to read for the
directory information. The default "find files"
are SYS:FNDDAT.FDF and SYS:FNDDAT.FPF if /FNDDAT
is not specified, otherwise default device is
DSK:, filname is FNDDAT, file types (extensions)
are .FDF and .FPF, directory is [-].
/[NO]HDSDIR Do [not] print the file's device and directory
information as a separate "header" line
immediately preceeding the directory listing for
each directory listed. Default is /NOHDSDIR
unless both /WIDTH is specified and /FLSDIR is not
specified.
/[NO]INDIRECT Do [not] format the directory listing output in
such a manner that it can be used directly as
command input to another program. Each file is
listed as "dev:file.type[directory]" on a separate
line; error messages are suppressed; summaries
are suppressed. Default is /NORMAL.
/LIST Use LPT: as the default output device.
/[NO]MARKS When reading a magtape, do [not] annotate each end
of file mark encountered. Default is /NOMARKS.
/[NO]MVOLUME When reading BACKUP or DUMPER magtapes, do [not]
ask the user to mount successive reels when end of
tape is encountered in the middle of a save set.
Default is /NOMVOLUME.
/NORMAL Print just the "normal" directory listing which
consists of the file name, file type, length,
protection, creation date, version (if non-zero),
and device and directory. /NORMAL is the default
listing mode.
/[NO]PRDEVICE Do [not] always print the device for each file
listed. Complete absence of the switch causes the
device to be printed out only when it is different
from the previous file's device; /NOPRDEVICE
never prints the device; /PRDEVICE always prints
the device.
/[NO]PRDIRECTORY Do [not] always print the directory for each file
listed. Complete absence of the switch causes the
directory to be printed out only when it is
different from the previous file's directory;
/NOPRDIRECTORY never prints the directory;
/PRDIRECTORY always prints the directory.
/[NO]PRVERSION Do [not] always print the file version for each
file listed. Complete absence of the switch
causes the version to be printed out only if it is
non-zero; /NOPRVERSION never prints the version;
/PRVERSION always prints the version (blank filled
if zero).
/[NO]RETRY Do [not] enable automatic error retry when reading
a file. /NORETRY will generate an I/O error
message even for soft read errors. Default is
/RETRY.
/[NO]REWIND When reading a magtape, do [not] rewind the tape
both before and after reading it. Default is
/REWIND.
/[NO]SBRMSG Do [not] issue the 'DRTSBR Skipping BACKUP/FRS
repeater record' warnings upon encountering a
BACKUP/FRS-formatted magtape repeater record.
Default is /NOSBRMSG.
/SLOW Prints a more detailed directory listing than
/NORMAL (hence it is slower to type) containing
the file name, file type, length, protection,
access date, creation time and date, I/O mode,
version (if non-zero), and device and directory.
Default is /NORMAL.
/[NO]SORT Do [not] format the ASCII directory listing in a
format suitable for reading and sorting. If /SORT
is specified the output listing file will contain
no tabs (only spaces); date information is
strictly numeric in descending precedence; all
error messages are suppressed from the listing
file. Default is /NOSORT.
/[NO]SUMMARY Do [not] print the directory listing summary.
Complete absence of the switch prints a summary
after each directory listed; /NOSUMMARY never
prints the summary; /SUMMARY prints only the
summary (and suppresses the regular file by file
directory listing).
/[NO]TITLE Do [not] print a columnar title line at the top of
each "page" of the directory listing. Default is
/NOTITLE for terminals and /TITLE for non-terminal
devices.
/TMPCOR List in old TMPCOR format.
/[NO]UNITS Do [not] print the file's device as a unit name
rather than a structure name (applies to disks
only). Default is /NOUNITS.
/WIDTH:n Sets the width ("n" characters wide) of the output
directory listing. DIRECT will output as many
separate file listings across the "page" as will
fit in the specified width. Default width is read
from the monitor for terminals, and 132 for
non-terminals.
/[NO]WORDS When listing the file's length, do [not] express
the file's length in units of words rather than
disk blocks. Default is /NOWORDS.
/WRITTEN Use the file's data size (how much data has been
written into the file) rather than the physically
allocated size when printing the file's length.
Default is /WRITTEN.
