	This directory contains all files necessary to build TAR, an RSX
utility to manipulate UNIX TAR floppy volumes, either in normal UNIX for-
mat or in Tektronix TNIX(8560) format. For further information on the capa-
bilities of this utility, consult TAR.DOC in this directory.
 
	This software is and remains the property of SSG and no rights or

	This software is being contributed to the DECUS RSX/SIG free of charge
and warranty. The user, in accepting this software, understands that it is
delivered "as is". SSG accepts no responsibility for its performance.
 
	SSG grants to the DECUS RSX/SIG and to the user a license to use and
modify this software subject to the conditions listed below. The user, in ac-
cepting this software, agrees to the conditions listed below.
 
				Conditions
 
  1) The user may use and/or modify this software at his own risk.
 
  2) The user may redistribute this software at his discretion provided
     that it is redistributed under the same terms and conditions under
     which it was obtained, i.e., free of charge and warranty, and provided
     that the SSG copyright notice is included in all such redistributions
     as well as an indication that the source is the DECUS RSX/SIG.
 
 
	TAR has been implemented in the SSG version of SUPERMAC, SCAT-11.
Since no attempt has been made by SSG to ensure compatability between SCAT-11
and SUPERMAC, this program may not assemble with the versions of SUPERMAC
available through the RSX/SIG. For this reason, a pre-assembled library
of modules has been included, TAR.OLB. Also supplied is an RSX-11M v3.2
task image of TAR along with documentation and command files. If you care
to assemble the sources, change all references to SCAT11 in the sources
to the appropriate SUPERMAC invocation, SMACIT.

	Release 2

	This version of TAR has been modified so that:

1. It will assemble and run correctly with the supplied version of
	SUPERMAC, and
2. It works with RX50 drives that are mounted foreign (e.g., by
	the supplied UTIL program).

	It is useful for communicating with VENIX or ULTRIX systems
using RX50 media since they typically do not have magtape.

	A sample command sequence to use the utility might be
something like the following (comments after the ";" characters
are not typed, only narrative):

INSTALL UTIL
INSTALL TAR		;INSTALL the two utilities

; physically place your blank RX50 in DZ1:

.UTIL FOR DZ1:		;mount the DZ: unit foreign
.TAR DZ1:/INIT		;initialize it as a UNIX volume

.TAR DZ1:=file1.typ	;copy file1.typ onto it
.TAR DZ1:=FILE2.TYP	;copy file2.typ onto it too

.TAR DZ1:/LIST		;list the floppy directory to see it's there.

; to go the other way omit the /INIT and use a command like:

.TAR =DZ1:file1.typ

;to get the file to RSX from TAR format.
