MARCView and Unblock

To install, copy the programs into a directory on your hard drive that
is in your DOS Path statement, or in the directory where your MARC
files are.

MARCView and Unblock cannot interpret directory names in the filename.
If MARCView and Unblock are in a directory on your path or in the
directory where your MARC files are, you can go to the directory where
the MARC files are and run MARCView and Unblock from there.

Both MARCView and Unblock are completely safe and do not modify their
input files in any way.

MARCView

To run, enter MV at the DOS prompt:

	MV<enter>

Filename to view will be requested by the program, or you can enter it
after the program name at the DOS prompt, as in

	MV OCLC.BKS<enter>

MARCView works on records in NISO-standard MARC format, used in libraries
throughout North America.  Records may be followed by additional characters 
such as return/line feed (not strictly legal in MARC), so long as all records
are followed by the same number of characters.

A maximum of 5,000 records can be viewed.  If the file is longer than that,
the first 5,000 records can be viewed.

MARCView will not read blocked records (such as those on tapes received from
bibliographic utilities).  Convert the file with Unblock and then use
MARCView.

If you do not find the Ctl-PgDn and Ctl-PgUp intuitive for Next and Previous
records, you may also use N for Next and P for Previous.  But the Ctl
combinations save a lot of hand movement.

The full list of commands is:

	PgDn           Scroll record down
	Home           Scroll to top of record
	Ctl-PgDn or N  Go to next record
	Ctl-PgUp or P  Go to previous record
	Ctl-Home       Go to first record
	Ctl-End        Go to last record
	G              Goto Nth record (you will be asked for record number)
	F              Find (you will be asked for word or phrase to find)
	Ctl-F          Find next record containing same word or phrase
	Ctl-P          Print currently displayed record (LPT1)
	X              Exit

The Find command searches in data only, not in tags or other content
designators.  It is an exact-match search (case matters).  Search begins
at current record.

Unblock

Creates a new file of unblocked records.  This file is given the filename
of the input file and the extension UNB.  For example:

        Input file: RLIN         Output file: RLIN.UNB

        Input file: UTLAS.BKS    Output file: UTLAS.UNB

The input file is unchanged whether Unblock terminates normally or
abnormally.

To run, enter Unblock at a DOS prompt (can be a Windows DOS prompt):

	Unblock<enter>

Filename to unblock will be requested by the program, or you can enter it
after the program name at the DOS prompt, as in

	Unblock OCLC.BKS<enter>

Blocksize must be 2080, with a 32-byte block header; one record per block.

If Unblock detects a problem in the input file, it will display a
"Nonstandard file" message, but all the records up to that point are 
unblocked, and can be viewed with MARCView.  However, moving to the
last record may cause MARCView to terminate.
