History of PopDBF Development
=============================
Future Features include (in order as they will be done):
--------------------------------------------------------
o Create database (almost finished!!!)
o Swap to disk or EMS leaving 2-3K footprint
o Network version (hopefully in version 3.8, finally)
o Modify structure
o Memo read/edit
Version 3.7 - Released October 15, 1990
---------------------------------------
o Added the following major functions:
- COPY STRUCTURE, copies all or selected fields to
new database
- DELETE FILE, to delete any file from the pick file
window
- PACK, physically deletes records tagged for delete
- ZAP, physically deletes ALL records in the
database
o The color scheme has been SIGNIFICANTLY changed. Also,
colors can now be configured along with the hotkey,
using POPCFG.COM. This program is now included with
ALL REGISTERED COPIES. If you like the old color
scheme use command line option /CO.
o The force monochrome colors command line option has
been changed from /M to /CM.
o The write file access command line option /W has been
replaced by /TW. You can now change any of the
"toggle" indicators (file access, field borders, insert
mode, case sensitivity) using the command line option
/T<B,C,I,W>.
o Pressing PgDn while appending a record will NOT move
back and forth between the last record in the database
and the new record. This was a bug.
o Fixed a bug, which occurred when pressing Alt-M while
in an already open READ-ONLY database. This will now
cause an access error.
o Fixed a bug which occurred when specifying a default
directory on the command line (/D) and did not also
specify the drive.
o Fixed a bug which ignored the action option (/A) if it
was specified after the passthru option (/P) when
PopDBF was already resident.
o When trying to access PopDBF while in a graphics
application, a chime will sound, indicating that your
request was heard, but can't be accommodated. Pop-up
over graphics will be supported in the future.
o Ctrl-U now toggles the record delete flag in the Browse
window, just like it does in the Edit window.
o Negative numbers are now supported.
o Support for FoxPro and dBase IV databases.
o The beep function was changed to be faster and quieter.
o When an error message is displayed, a chime will now
sound.
o Enter key on numeric keypad now works like Return key.
o Moving to <parent> directory now positions selection
bar on that directory.
o Command line options may be combined (i.e. /mwz).
However, options with variable length arguments must be
last (i.e. /p). No spaces may separate options /D and
/P and additional text.
o Arrow indicators were added to windows to provide
information on valid directions of cursor movement.
o Default action now displays as a descriptive word.
o Video routines have been optimized and speeded up.
o Hot keys for frequently used databases (Alt-1 etc.) can
be used from anywhere in the program and previous
positions and modes are retained. Also, Alt-dash and
Alt-= can be used to access up to 12 frequent
databases. In addition, each directory can contain a
.FRQ file so that the frequently used databases can be
application dependent. If a .FRQ file is not found in
the current directory, PopDBF will look in the
directory where POPDBF.COM is located.
o Commercial version now includes KBSPEED, a keyboard
speed-up program, and ARROW, a TSR position display
program, which are NOT included in shareware registered
copies.
Version 3.6 - Released February 8, 1990
---------------------------------------
o Commercial version includes a program, POPCFG.COM, to
configure the hotkey. This is NOT included in the
shareware version!
o Path option from Pick File Window has been replaced by
Dir option which functions like the change directory
command in DOS. This same option is now used to change
drives just as you would in DOS.
o You may enter a specific file, including drive and
path, by pressing F3 from Pick File Window.
o Added command line option to specify default action,
/A. The default action is taken for each file when
Enter is pressed. It can be changed at any time by
pressing F5.
o The frequently used database file can optionally
specify the action to be taken when the appropriate
hotkey is pressed (Alt-1 thru 0). If the file name, in
POPDBF.FRQ is preceded by one of the following letters,
A B E or S AND a space the action taken will be the
same as pressing Alt and that letter.
o Added a warning when leaving Edit or Append and changes
that you have made have not been saved.
o Changed all prompts for input to use left and right
arrow keys, home, end, delete and insert. CTRL-Y will
always blank input field.
o Changed the pass-thru function so that it can be used
even if PopDBF is already loaded in memory.
o Pressing PgDn while in Append will now position you to
the last record in the file in Edit mode. Pressing
PgDn in Edit mode when on the last record will take you
into Append.
o Pressing ESC from Structure, Browse, or Append/Edit
will always return you to the Pick File window.
o Fixed problems caused by not recognizing an extended
keyboard. These were primarily in Edit and prevented
certain key combinations from doing what they were
supposed to do (i.e. Ctrl-Delete).
o Fixed a bug which occurred when Ctrl-PgUp or Ctrl-PgDn
was pressed while appending an empty database.
o Fixed a bug which allowed invalid months and days in
date fields.
o Fixed a bug which zeroed numeric fields when the RETURN
key was pressed after editing a preceding date field.
o Fixed a bug caused by insufficient video storage and
occurred when using help while editing a record.
o Fixed the /D command line, which option did not work
correctly when no drive was specified.
Version 3.5 - Released November 3, 1989
---------------------------------------
o Program is now just one version, EDIT. However, a
READ-ONLY version is available upon request.
o Made necessary changes to join ASP. Demo version is
fully functional with the only difference being the
registration information screen, not included in
registered copies.
o You no longer have to be in the directory where
POPDBF.COM is located when you load PopDBF into memory
for context sensitive help to be available. However,
POPDBF.HLP does need to be in the same directory as
POPDBF.COM.
o The default number of fields has been reduced from 128
to 64 and the default edit buffer has been reduced from
2K to 1K. This is just to reduce the default memory
footprint. You can specify /F128 and /E2048 on the
command line to use the old values.
o To make the pop-up more instantaneous, only directories
WITHOUT an extension are available in the Pick file
window.
o You can now get from any major area to any other major
area by directly pressing some ALT key combination.
The major areas are: Append records, Browse records,
Edit records, File selection, view Structure. Pressing
ALT and the proper capital letter will take you to that
area.
o Pressing the ALT key will cause the status line to show
a menu with the areas described above and the
appropriate letter highlighted as well as other
options.
o Help has been greatly improved both in content and
functionality. You can now scroll up and down through
help and hotkey out of it.
o You can now change the file access mode from anywhere
by pressing Alt-M. File access mode must be read/write
to Edit or Append.
o Frequently used files feature. A file named POPDBF.FRQ
can contain up to 10 fully qualified database file
names for access from the Pick file window using Alt-1
through Alt-0.
o Current field and record are now shown with their
corresponding maximum (i.e. 10/200).
o While finding text the record number in the window
border will reflect the current record being searched.
o Added ability to search on a selected field or fields.
You can also force the search string to be found
entirely within one field to avoid finding part of a
string in one field and the rest of it in adjacent
field.
o Changed the key that moved the cursor to the first
blank character after any data in a field in Edit from
Alt-End to End. Ctrl-E will now move to the last
position in the field.
o Changed the century toggle key from Ctrl-D to Ctrl-C.
o Added two new command line arguments. /D will allow
you to specify an initial directory and /Z will start
the Browse window in zoomed out (expanded) mode.
o Fixed an error which occurred when deleting some
characters in a field while in Edit and then pressing
the End key. The error did cause a Divide Overflow
error, which forced a reboot.
o Fixed an error which occurred when no files or
directories were found in the current directory on the
current drive. Now zero files are displayed and you
can use F3 to change drives or hotkey out.
o Fixed an error in the find next which didn't beep when
sitting on the last record in the file, but should
have.
o Fixed an error which occurred when all fields in the
structure were marked (numbered). EDIT would perform
strangely when using the hotkey to exit and re-enter.
Version 3.4 - Released August 17, 1989
--------------------------------------
o Added message when trying to edit record in read mode.
o Added Alt-END to go to first position AFTER last non-
blank character.
o Fixed a bug that caused underlying applications to
terminate when exiting PopDBF. This really got fixed
on 8/24/89, but only a few people fell between the
cracks.
Version 3.3 - Released July 24, 1989
------------------------------------
o Added the ability to view an index expression from the
File Selection window.
o Added ability to specify a default file specification
by pressing function key F4 from the File Selection
window.

record being appended or edited. (EDIT version only)
o Added ability to move a word at a time. (EDIT version
only)
o Added system date stamp. (EDIT version only)
o Fixed many minor bugs in the edit routine. (EDIT

o Smaller default buffer sizes.
Version 3.2 - Released June 17, 1989
------------------------------------
o Fixed a bug which occurred when editing a character
field that was longer than 60 bytes. The field was
edited correctly, but the cursor was positioned
incorrectly.
Version 3.2 - Released May 31, 1989
-----------------------------------
o There is now a "pass-thru" mode so you can use PopDBF
without installing it into memory. You may also
specify a file name with this option and go right to
browsing that file.
o Should work with all dBASE IV files.
Version 3.1 - Released May 27, 1989
-----------------------------------
o Fixed bug when assigning a mark and no other marks
exist.
o After panning to the right, executing a ZOOM did force
browse display to begin with first field, but now
works.
o You can now adjust the size of the read buffer in
bytes, the size of the edit buffer in bytes (EDIT
version only), and the maximum number of fields. This
is done by specifying command line parameters when
loading PopDBF into memory.
o All windows now have shadows to give a 3-D look.
Version 3.0 - Released April 26, 1989 (first release to BBS)
------------------------------------------------------------
o Included the EDIT capability!!.
o Fixed the find-next to start at the record after the
one the bar is on instead of the second record from the
top of the window.
o Changed find and find next to be F7 and F8 for easier
operation.
o Failure of either a find or find next now causes the
bell to sound.
o Added to /W switch to start in EDIT mode.
Version 2.55 - Released April 9, 1989

o Pressing F10 from FILE SELECTION will now work
correctly, even if an alternate path had been specified
Version 2.54 - Released April 6, 1989
--------------------------------------
o Fixed a bug in the find routine that could have caused
system crashes.
o Pressing the hotkey while entering find text now exits
back to the browse window instead of beginning the
find.
o You can now assign sequence marks to unmarked fields.
o When printing records you may elect to limit the
printing to only those records in the print range that
meet a previous find condition.
o Alt-F1 will pop-up a help window with information about
general keyboard movement.
o Pressing PGDN in file selection or view structure when
there are less than a window's worth of entries now
moves the bar to the last entry in the window.
