WSSINDEX Tips
Version 3.1 for WSSINDEX version 3.1
If you have found any clever ways of using WSSINDEX, or any other
programs which increase the program's utility for you, please
report them to me and I will add them to the next version of this
list. Some commonly asked questions are also answered in this
list.
1. If you have a tape backup system which can "fool" DOS into
thinking it is a disk drive, you can probably process it with
WSSINDEX. For example, I found that I could read directories
from a Tallgrass tape unit if I loaded the Tallgrass TMS
program first.
2. The core resident public domain utility CP2 can be used to cut
a line from the viewfile display for pasting into the new
comment field. I do not guarantee compatibility with this
program. It seems to work on my system, but I do not have
source code for it and cannot maintain it.
3. If you want to print a diskette sized directory of information
for a single disk, set your printer for compressed printing
and configure WSSINDEX for page length and width to give a 5"
by 5" page. Print the database selecting only files from the
desired disk.
4. If you want to associate comments with subdirectories, you can
put a zero length file named ! in each subdirectory. This
file will sort alphabetically before any other (legally named)
file. If your system objects to copying a zero length file,
try the shareware program FFM or other file utilities. My
system will only copy such a file if it is one of at least two
matching files in a wild card copy command.
5. Once the in-core database has been sorted, it stays sorted the
same way until a disk is added or removed, so you can often
specify sort option 0 to save time. This is especially useful
if you enter an invalid selection option in a print request
and get kicked back to the main menu after sorting.
6. I find that a large library of floppy disks is easier to
maintain if I assign a unique serial number to each disk and
make it the leading characters of the volume name. Not only
is it easier to look for a disk which has both a unique number
and a descriptive name, but it is easy to jot down the disk
number whenever I update a disk, so I have a reasonably
complete list of disks which have been changed and need to be
re-entered into the database.
7. The predefined category strings triggered by hitting
Alt+letter can be used just about anywhere a character string
is required. For example, if you have several databases, you
can put their names into category strings and use a simple Alt
keystroke to enter their names when you want to read them in.
Or if you want to select files by category, you can use the
same keystroke you used to enter the category in the first
place.
8. If you are a software "collector", you may eventually run into
the 16K file limit, or run out of memory, or just suffer from
slow processing of large databases. If you foresee any chance
of needing to use multiple databases in the future, you are
better off setting them up at the start. It is simple to
merge two databases if you want to process everything at once,
but the only way to split a database would be to remove
selected disks from the database one at a time.
9. The configuration files are not guaranteed to be compatible
from version to version, although I try to make it possible to
read and use most of the information in an obsolete format
configuration file. You should get an error message if you
read an old, incompatible configuration file, but due to a bug
in all 2.xx versions, the message never appeared. You should
always review the configuration when trying out a new release
of WSSINDEX.
10.With the addition of the option to extract information from
ARC files, you may want to re-index all disks which include
such files. Here's a simple way to generate a list of all
disks which contain ARC files:
1. Configure WSSINDEX to print only the volume name, and
with a huge page length to suppress all but the first
title.
2. Print your database to disk file ARCONLY.PRN, sorted by
volume name, selecting filename *.ARC.
3. Run the following BASIC program to strip off file names
and eliminate duplicate volume names (it will terminate
with an error message when it hits the end of file).
10 OLD$=""
20 OPEN "I",#1,"ARCONLY.PRN"
30 LINE INPUT #1,JUNK$ : LINE INPUT #1,JUNK$
40 LINE INPUT #1,V$
50 V$=MID$(V$,15)
60 IF V$<>OLD$ THEN LPRINT V$ : OLD$=V$
70 GOTO 40
