BTFILER Installation Instructions/
Last minute notes.
All BTFILER files are found in a file called BTFL13.ZIP. You
should extract all files from the ZIP file and make sure all
files are found on the PATH.
Note that the program currently has been tested with variable
length files as large as 25000 bytes without unpleasant side
effects on a system with 540 K of free memory. The only problem
is that less than a full screen of data will appear.
An undocumented feature is that while opening a file, the
directories specified by the environment variable BTFILEPATH are
also searched.
If you have any trouble seeing the menus, try resetting the
colors (Set Colors under the Options menu). If you are unable
to see the menus well enough to set the colors, please copy the
file CINSTALL.B&W to CINSTALL.DAT. This will install the
standard green screen color set.
If this software is more than 9 months old, please send you name
and mailing address, along with a blank diskette and postage for
2 ounces and I will send you the latest version of the
software. I understand that shareware tends to live on forever,
but I would like you to have the best possible impression of my
work, and while I am not currently aware of any bugs, I can
pretty much assure you that the software will be even better 9
months down the line than it is now. The address is:
Access Microsystems Inc.
404 Midstreams Road
Brick, New Jersey 08724
Thank you!
What's New?
04/03/92 Add ability to use INSERT and DELETE in the Hex/ASCII
edit screen. Also add F1 support in Hex/ASCII edit.
04/02/92 Add support for Header Rebuild. PLEASE NOTE THAT THIS
IS NOT FOR FOLKS WHO DON'T KNOW WHAT THEY ARE DOING!
In any case, the Rebuild Header option on Test/Rebuild
on the main File menu should only be used after you
have tried to do a normal rebuild. To rebuild the
header, you MUST have a btrieve file available with
EXACTLY the same file structure as the one whose
header you wish to rebuild. After the rebuild of the
header completes successfully, you will be brought to
the file rebuild screen with the file to rebuild
already filled in. Also, the drive where the work
file should be built during a rebuild can also be set
now to allow for the rebuild of a file that is larger
than the free space on the disk where the file
resides. REMEMBER: During header rebuilding you can
just as easily damage a good file as fix a bad one!
You should make a backup of the file before you try
the header rebuild so you can try other methods if
BTFILER fails.
Also, there have been several small fixes to allow for
better recovery of variable length files.
03/27/92 Fix odd display of % Utilization when file has 0 records.
03/26/92 Change behavior of abandon during COPY operation when
ESC pressed. Also add ability to use PREALLOCATION=
line (optional just after FREE SPACE THRESHOLD=) in
.BTB BTrieve Build description file. Allow 0 value in
FREE SPACE THRESHOLD= line to allow 0 free space
threshold.
03/25/92 Open Btrieve "source" files in various places in Read Only
mode, so that the file is more likely to be able to be read.
03/19/92 Add color customization, ensure colors updated properly
when using a program like Carbon Copy with differing
video adaptors. Several minor tweaks. Version 1.31.
03/15/92 Add error reporting to some areas not previously
reporting errors. (For instance, when you
"View Begining with").
Place up-to-date copy of BTFILER.MSK into ZIP.
02/29/92 Fix problem with packing of files with duplicates
allowed in key 0. BTFILER was reading the records
just fine, but was adding them to the packed file
in such a way that the duplicates in key 0 were
causing UPDATES, not INSERTS. "Always Insert" flag
added to PACK and COPY screen. (Thanks to Mike Trill
from CompuServe for pointing this one out.) Also,
add COPY option for one stop export/import into new
format.
(In the PM) Cause a clone to be built in copy if
destination does not exist.
02/26/92 Fix silly display problem when last record in file
deleted.
02/19/92 Fix status 22 occuring in error on variable length
records. (Internal testing).
02/17/92 (Happy Washington's Birthday!) Little changes
resulting from extensive testing. Expand size of
possible keystroke file to 200. Make the
/c:myconfig.cf2 file the file written to, if
specified on the command line. Also add ability to
specify MANUAL as a key type.
First general release of 1.30.
02/11/92 New version fixes. Fix display problems for lines
shorter than 80, fix odd behavior when last record is
deleted (again...this reared it's ugly head before...)
and ensure that highlighting does not disappear during
record delete. Still BETA, for brave souls who do
frequent backups (just in case!).
02/07/92 New Version! Ver. 1.30 adds ability to use a file
of keystrokes to run the program (Batch mode). See
BTCLONE.BAT and BTRESET.BAT for info on creating files.
Also, the open mode of the files Browsed/Edited can be
set. In addition, the default filename mask can be set.
If you already have edited a file, you can get back to
the default filename mask by pressing <F9> in fields
where the status line says you can. You can also
clear out any data entry field by pressing <CTRL-C>.
There are also some memory allocation fixes.
Features added include: Transactions can be started,
abandoned or finished out properly (although the
program in BETA will allow you to try to do silly
things while in a transaction, and simply fail with an
error message rather than letting you know up front.)
Supplemental index addition is now supported. See
SAMPLE.BTS (Btrieve Supplemental) for details.
BETA RELEASE!
01/27/92 Fix problem that happens during PACK with SHARE
loaded. PACK works fine, but error was reported
at the end of the process, and temporary files were
not deleted. (Thanks to: Carl in Orlando).
01/22/92 Bug fix. Fixed problem with screen display if last
record on screen deleted. Problem might have just
been added with the 1/20/92 change to the program.
(internal testing).
01/20/92 Bug Fixes. Also, change version number to 1.21 to
ensure I will know if you have the latest version
if you call. Fix problem with saving of variable length
records. If you edited the first record in a variable
length file, made no changes, and edited that record
again, the record length would be reported as the
maximum record length specified in the "Set Misc.
Parameters" section. (Thanks to: Brian Levine of
Orlando) Also, remove "<ESC> to Exit Help" message when
you have exited help. (Thanks to: Steve Checkosky in
Syracuse) Fixed memory allocation bug while deleting
records. (Internal testing).
Along the way, added a feature that allow for setting
of length of a variable length record when you go to
save it. Uses current length as default, and will use
current length if length is too long (longer than
Longest variable length record setting in "Set Misc.
Parameters") or too short (shorter than fixed length
portion of record).
Also, see the documentation regarding ways to register
BTFILER if you must use a credit card. You may do so
through CompuServe or the toll free number listed in
the documentation.
01/17/92 Bug fixes/Silly Spelling error fix. Fixed problem that
caused an Abnormal Program Termination if statistics
were requested on a file with 0 records. (Thanks to:
Jamie Bozzo from Mass.) Fixed spelling errors in
BTFILER.MNU and BTFILER.HLP.
01/04/92 Bug fixes. Fixed problem that could cause NULL Pointer
error (Thanks to: Brian Levine of Orlando) and problem
that could allow editing of the byte in memory just
BEFORE the buffer for a Btrieve record (internal testing).
12/20/91 NEW VERSION (1.20). Help available when BTRIEVE
errors occur, explanations of BTRIEVE errors available
while listing errors. New features include Set and
Clear owner, Statistics on a Btrieve file,
improvements to the Import/Export utility (a late
version 1.10 add-in). Print documantation from the
menu. Also, Btrieve Page Size Calculator, Create
Btrieve fiels for ASCII BTrieve Build (BTB) description
file. Like BUTIL -CREATE but with MUCH better error
reporting!
12/05/91 Various fixes. Fixed some oddness if the menu
control, fixed a problem with error reporting (changes
to BTFILER.BER), and made the HEX/ASCII edit routine
allow display and edit of 256 bytes at a time, double
the previous display.
Changed system behavior during EXPORT. Prompts user
to see if s/he wants to delete destination ASCII file
before doing export, or export is abandoned. This was
needed since there could be problems if the
destination ASCII file was created by BUTIL -RECOVER,
since this results in a literal control-Z written to
the file, which will cause problems for BTFILER during
Import.
While browsing a file, the HOME and END keys work to
put you at the beginning and the end of the file,
respectively.
12/01/91 Import/Export is added to the FILE menu.
