This archive contains DESQview PIFs, supporting batch files, and
other various odds and ends for programs you may wish to use with DV Tree.
The examples are not intended to be usable in all cases without
modification, and a certain degree of knowledge of DESQview PIF setup and
batch file programming may be required.
A portion of the contents of this archive are generally relevant
to users of programs such as PKZIP, LHARC, PAK, and other archiving
utilities; together, these examples provide ways to use DV Tree and
DESQview to manage archive files in a multi-tasking fashion. Some of the
batch files execute a small included utility called DVTUPDAT.COM. This
utility's one purpose in life is to request DV Tree to refresh its file
directory display(s). It may be run from any window within DESQview, and
will simply do nothing if DV Tree is not present. If multiple copies of DV
Tree are running, the one started first will receive the message.
The best way to get started is to copy these files and PIFs to the
DV Tree directory, preferably C:\DV\DVTREE as that will require the least
amount of change. You should copy DVTUPDAT.COM to a directory in the DOS
PATH, and also ensure that all archiving/dearchiving software you use in
the DOS PATH as well. The examples here come in the following pairs, with
the suggested DV Tree DESQview function codes in parentheses:
UA-PIF.DVP/UNARCHIV.BAT(%c%y %p%O)
This batch file takes the pointed-at file extension and checks for
.ZIP, .ARC, .LZH, .ZOO, or .PAK. When it finds a match it passes the rest
of the input, the full pathname of the pointed-at file, to the appropriate
de-archiving utility (PKUNZIP, PKXARC, LHARC, LOOZ, PAK). If the screen is
split, the archival files will be placed in the directory shown in the
opposite split. The PIF has a '?' on its parameter which causes it to
pause before starting the batch file, in this case to allow up to seven
individual filenames or masks to be specified to limit the scope of the
file extraction. The PIF has a memory size of 160K; this may be reduced
to 128K if the PAK utility is not used.
LA-PIF.DVP/LISTARCH.BAT(%c%y %p)
This batch file processes a file extension and executes the
appropriate program in the same manner as the previous example. Files are
de-archived to a temporary file (LZ.XYZ), which is then LISTed. This file
will require editing if your LIST program is not called LIST. When list
is exited, the temporary file is deleted. Again, the 160K memory size is
to accommodate PAK.
ZL-PIF.DVP/DVLZIP.BAT(%c%p)
This is a simplified version of the previous example, meant only
for .ZIP files and tailored to common needs (that of viewing .DOC and
README or READ.ME files in newly acquired archives.) The same pause
occurs at startup, but if nothing is entered, the batch file tries to
extract only *.DOC and READ*.*.
CZ-PIF.DVP/DVCZIP.BAT(%c%p)
This very simple batch file does nothing more than execute a
program called FV and pause. FV is a shareware utility by Vernon Buerg,
the author of LIST, and all it's meant to do is list out the internal file
names of an archive file of any variety. It does this very quickly, in
very little memory, and I highly recommend it - distributed as FVnnn.*
(ex: FV132.ZIP), it's also been included in the more recent releases of
the LIST program (LIST75A, for instance.)
Another pair of example files are enclosed for users of
WordPerfect 5.1 wishing to use DV Tree's reload feature for this
application. WordPerfect, does not easily lend itself to any of the usual
techniques as it requires a separate prompt to change directories, and
then a 'name match' to get to the file you're looking for (you also must
me, by the way, in 'short' directory mode to get to anything that's not
already a WP file.)
The following is workable code string for WordPerfect that uses a
script to trigger a WP macro:
%c%p%A&z&2%d%e%s%e.
The &z code kicks off the {255} script contained in WP-SCRIP.DVS,
and the script uses ALT-F10 to run the Word Perfect macro TLOAD.WPM. The
macro pauses first for a directory name (supplied by %d%e), then a file
name (%s%e). Please note the 2 second delay after the &z. If you use WP
and would like to try this, you of course must move TLOAD.WPM to your WP
macro directory, and WP-SCRIP.DVS to your \DV directory (If you've already
got scripts for WP, however, you might do better just to 'LEARN' the {255}
script manually (ALT-F10/load TLOAD macro).)
