This is a short file describing the installation of VLT.
Other files you may want
------------------------
VLT uses certain other files that are not distributed with VLT. None
of these are absolutely required, but some features are not available
if they are not there.
1. VLT will complain if it cannot find the external file transfer
protocol library (XPR) that is currently selected. While it seems
that XMODEM and Kermit are built in, they really are not. Despite
the complaint, VLT will run fine anyway (but can't transfer files).
It would be good to acquire the freely distributable XPR libraries
of your choice. Currently, there exist ones for XMODEM, Kermit,
ZMODEM, Jmodem, CompuServe Quick-B, and YMODEM. An ASCII XPR
is included (xprascii.library).
2. The VLT "online docs" are in AmigaGuide. If you do not have
AmigaGuide.library, you should install it on your system.
3. Some of the ARexx programs that come with VLT require that you
have rexxarplib.library version *3.0* or later. Earlier versions
of rexxarplib.library will not work correctly. Rexxarplib.library
is available on BIX and on the anonymous FTP site
ftp.slac.stanford.edu, as well as various online services
and BBS's.
4. If you intend to play with FifoBBS.rexx and similar Fifo: based
utilities, you must install the Fifo: handler by Matt Dillon.
Not needed for normal operation.
5. There are lots of nice VLT scripts that you may be interested in,
written by others. Some implement phone books (see however also
the one included with this distribution), others, automated
up/download facilities for on-line services.
Installation: First time users (but upgraders, read anyway!)
------------------------------------------------------------
If this is the first time you have downloaded VLT, then the installation
is very simple.
1. You have already extracted all files from this archive. You should
have done this using the command:
lha -x -a x vltj5867.lha
or
lha -x -a x vlt5p867.lha
depending on whether you obtained VLTjr or VLT.
If you did not do it that way, please start over. It is important
to create all subdirectories, and also the -a part is necessary.
2. Now that you have extracted all files, you should see, from the
Workbench, a drawer called VLT. Drag this drawer to the place where
you want VLT to live.
If you want to install VLT on a floppy, consult the printed manual
(see vlt/docs/VLT.guide for how to obtain it). You will have to
delete a lot of files on a Workbench floppy to make room for VLT.
3. You are now essentially done. (See however the section on other
files VLT needs, above). If you want to make VLT resident, see
also point 4.
When you open the VLT drawer, you will see the VLT icon, and also a VLT
script icon. Double click on VLT to start it, or double click on the
VLT script icon to see how that goes.
Next, note the "Help" item in the VLT main menu. It will open (if you
have AmigaGuide.library) the VLT on-line documentation.
Note, that most files that come with this archive do not have icons.
If you select "show all files" you can browse around and see what else
there is. Of special interest is the docs drawer, which has the
previously mentioned VLT AmigaGuide documentation. This guide
assumes that you have the manual for the previous version of VLT,
which can be obtained free of charge from SLAC. See the guide for
details. Each subdirectory has a brief readme file explaining what
all the files in that subdirectory are for.
4. If you intend to make VLT resident, then you must assign vlt: to the
directory that contains VLT. I.e., if you copied the VLT drawer to
your work: partition, then you must assign VLT: to work:VLT. Add the
line:
assign VLT: work:VLT
to your startup sequence.
5. If you run from a shell a lot, you probably want to add a path to the
directory that VLT lives in. Add the line:
path add work:VLT
to your startup sequence, if that's where VLT's executable is.
Upgrading from VLT version 5.576
--------------------------------
If you are upgrading from VLT version 5.576, then the installation is
also very easy. That is, if you installed VLT 5.576 in a directory all
by itself, as recommended. If you did not, then skip to the section
on upgrades from older versions of VLT. Again, for floppy installation,
see the printed manual.
1. Rename your current VLT drawer to "oldVLT"
2. Execute step 1 above.
3. Now that you have extracted all files, you should see, from the
Workbench, a drawer called VLT. Drag this drawer to the place where
your old VLT drawer used to live.
If you changed any of the files that came with the previous version
of VLT, copy them from the oldVLT drawer to the corresponding place
in the VLT drawer. This likely includes the files VTPrefs.dat and
in the case of the full VLT, TekPrefs.dat in the s drawer.
4. Now execute steps 3, 4 and 5 above as necessary.
5. You can now delete the oldVLT drawer, unless you want to keep it for
a while as a backup.
Upgrades to older versions of VLT
---------------------------------
If you're upgrading from an older version of VLT you have to make a
decision first. You can either install VLT in a directory somewhere,
with all the files it needs, or you can install VLT like you
installed the previous versions. If you want to take the easy way
out, just install it the way you installed it previously (i.e., devs
files go to devs:, libs files to libs:, s files to s: etc.). Note
that in that case you want to combine the scp files and rexx files
all into rexx:. The docs files should go into the same drawer as the
VLT executable.
Alternatively, you can take the opportunity to clean up your system
some. In principle the installation then is similar to the way
described above for new users, but you probably have lots of files of
your own that you want to copy to subdirectories in the new VLT
directory. But you have to be careful to not overwrite the new files
that came with VLT with the old ones you already had - unless you
made modifications and want to keep your own version.
Here's a possible installation sequence:
1. Unpack the VLT archive as described above.
2. Make a directory called, say, work:vltnew . Also make directories
work:vltnew/rexx and work:vltnew/scp .
3. copy rexx:*.vlt work:vltnew/rexx
copy rexx:*.scp work:vltnew/scp
Also copy all other VLT-related rexx files to work:vltnew/rexx .
4. From the Workbench, drag the VLT drawer that was created when you
unpacked the archive, to work:. You should now have a VLT and a
VLTnew drawer on work:.
5. From the CLI, do:
copy work:VLT work:VLTnew all
6. Now delete work:VLT as follows:
delete work:VLT all
7. Now rename VLTnew to VLT:
rename work:VLTnew work:VLT
8. Now copy the configuration files:
copy s:VTPrefs.dat work:VLT/s
copy s:TekPrefs.dat work:VLT/s
If you made changes to s:TekProlog.ps, make the same changes again to
work:VLT/s/TekProlog.ps.
Delete these files from s:.
9. Copy all the XPR libraries you have, if you wish, to work:VLT/libs .
Then delete these files from libs:.
If you have other programs that need access to the XPR libraries,
it is probably better to leave them in libs:
However, you can now delete from libs: the following libraries:
review.library, strokefont.library, duplexfont.library and
simplexfont.library.
10. If you wish, you can now delete all VLT specific fonts from fonts: .
delete fonts:vlt* all
11. If you intend to make VLT resident, make a VLT: assignment, as in
the "new user" case. If you run from a shell a lot, add the
directory VLT lives in to your path (see new user installation points
4 and 5).
12. If you find that VLT in certain cases can't find certain files, read
the section about "path searches" in the manual carefully. You
can almost always make VLT: find files by making some more
assignments, or by consolidating files in certain directories, or
by eliminating directories you're not actually using that VLT finds
anyway. If you don't have the printed manual yet, this information
is also in the VLT5p576.doc file.
This completes the VLT installation.
