IRAF V2.11.2 PATCH - August 1999

    VMS/IRAF (for both the DEC Alpha and for VAX/VMS) was updated to IRAF
V2.11.2 in July-August 1999.  A full install is necessary to install the new
version.  See the installation guides for instructions on how to do a full
install.  If you are upgrading, be sure to save your local site dependent
files (in DEV and HLIB) first, and diff/merge them after the upgrade.

See the URL http://iraf.noao.edu/v2112revs.html for a detailed list of
what is new in V2.11.2.

RECONSTRUCTING THE VMS/IRAF BACKUP SAVE SET

    The VMS/IRAF distribution is contained in several VMS BACKUP save sets
which have been compressed using the "zip" archive utility.  VMS executables
for the zip and unzip programs for both VAX and AXP are provided in the
"utils" subdirectory.  The BACKUP files have been zipped using the "-V" flag
to preserve the save set file structure.


USING FTP

    From your VMS system transfer the files in binary mode to your working
directory.  Here is a suggested procedure to create the IRAF tree from the
save sets. If you have a DEC Alpha machine only, you would not need the
files with suffix '_VAX' in the rootname:

	- Copy the unzip program from the VMS7/utils directory. There are 2
	  versions of the binary files according to your machine architecture
	  (VAX or AXP).

	- The files available in the ftp directory are as follows:

	  as_vms7_gen.zip  		# "All Sources" (including NOAO pkg)
	  ib_vms7_alp.zip		# Core IRAF binaries for Alphas
	  ib_vms7_vax.zip		# Core IRAF binaries for VAXes
	  nb_vms7_alp.zip        	# NOAO binaries for Alphas
	  nb_vms7_vax.zip   	        # NOAO binaries for VAXes 

        - set unzip: 'unzip :== $disk:[utils]unzip_alpha.exe'

	- unzip the files, example: 'unzip ib_vms7_alp.zip'


INSTALLING VMS/IRAF

    Proceed with the installation using the disk save set.  Full instructions
for the VMS/IRAF installation are given in the VMS/IRAF Installation Guide.
A Postscript version of this manual is provided in the file vmsiraf.ps.Z in
the archive directory.  The installation is identical to that described in
the manual, except that BACKUP is run on the disk save set, rather than on
a tape file.


Reading the BACKUP save set

    A listing of a backup save set reveals the complete pathname of each 
file including for logical disk name. To restore into your system you
need to use the 'select' qualifier to exclude the diskname in the restore
process. For example:

backup ib_vms7_alp.bck/save/select=[iraf...] [...]/own=iraf/prot=w:r

    This command restores the files from the disk file save set named 
vms.bck to the current directory creating subdirectories in the same
order as they are in the save set, changing ownership of each file and
giving read access to the world.

NOTES added since the release.

[TBA - watch this space for last minute notes on any problems found since
the release]

SAOIMAGE. To run saoimage you need to have a copy of the file
	  [iraf.dev]imtoolrc. in your login directory with the
	  name '.imtoolrc' if you want to add your own image
	  display sizes. Otherwise the logical name IMTOOLRC
	  should be defined as

	  define imtoolrc irafdisk:[iraf.dev]imtoolrc.

	  and not the way it is defined in the file 
	  irafhlib:irafuser.com. Make sure you redefine
	  'imtoolrc' after you have ran irafuser.com.
