OVERVIEW 2.20 DOCUMENTATION INTRODUCTION
SECTION 1: INTRODUCTION
Thank you for your interest in OverView!
OverView is a hard disk and file maintenance utility for IBM
Personal Computers, Personal System/2 (tm), and other compatible
computers which run the PC-DOS or MS-DOS operating system.
OverView gives you simple, straightforward commands to accomplish
everyday file operations such as copying, renaming, erasing, etc.
OverView removes the guesswork from file maintenance tasks by
displaying the files on your disk in a tabular format that is con-
tinually updated in response to your changes. OverView speeds up
time consuming disk clean-up and maintenance sessions because your
current options are always at your fingertips.
OverView is a hard disk and file maintenance utility, plain and
simple. It gives you the ability to execute DOS commands, but it
does not pretend to be a full featured DOS shell that simplifies
(and sometimes hinders) all DOS functions. Nor is OverView a
memory resident program that can be called up via "hot" keys. Both
these constraints were designed into OverView to keep it as direct
and unencumbered as possible.
You'll find that OverView is most useful on computer systems that
have a hard disk for data storage. OverView works just fine on
floppy disk based systems, but the file maintenance needs of floppy
only systems are just not as great as hard disk systems. Few
people have multiple directories and hundreds or thousands of files
on floppy disk systems.
This document describes the installation and usage of OverView
version 2.20. The document describes many features and functions
of the program, but there is no better way to learn the program
than by using it. Once you begin using OverView, you'll discover
more about how it works from the on-line help facility and by
experimenting with the various commands.
In addition to the standard file and disk maintenance functions
(copy, rename, erase, etc.), OverView has many other useful
features including:
* Supports from 1 to 6 windows allowing as many as 6 directories
(or disks) to be displayed at the same time.
* A directory tree display that shows your disk's directory
structure in an easy-to-understand graphical layout.
* Show-all and show-sub display functions that allow all files on
the current disk or under the current directory to be accessed as
if they were in one directory.

Personal System/2 is a trademark of IBM Corporation.

OVERVIEW 2.20 DOCUMENTATION INTRODUCTION
* A File view function that displays files as ascii text or in
hexadecimal dump format.
* A full screen interface with user selectable colors.
* On-line help available whenever and wherever OverView is waiting
for user input.
The best way to see just what OverView can do for you is to try it.
Since OverView is sold under the "try before you buy" shareware
marketing concept, you can do just that, right now, and without
spending any money up-front.
DOCUMENT CONVENTIONS
Throughout this document, references to OverView menu selections
are surrounded by brackets ([ ]) and have vertical bars (|)
separating entries from different menus. For example,
[Other | Setup Parameters | Screen Colors]
represents selecting the "Other" entry from the top level menu, the
"Setup Parameters" entry from the Other submenu, and the "Screen
Colors" entry from the Setup Parameters submenu.
Repetitive references to the same menu selections are sometimes
abbreviated by using "..." to represent the initial menu entries.
For example, the above menu selection could be shown as
[... | Screen Colors]

OVERVIEW 2.20 DOCUMENTATION SHAREWARE CONSIDERATIONS
SECTION 2: SHAREWARE CONSIDERATIONS
This section follows the introduction because it's very important
to the continuing evolution and support of OverView. This section
doesn't tell you how to use the program, or even how to install it.
What it does tell you is how to become a registered user once you
decide that you like the program and want to use it on a regular
basis.
OverView is distributed under the shareware marketing concept, it
is not free software and it has not been released to the public
domain. The documentation, executable images, and all other files
distributed with OverView are copyrighted.
Shareware is a way of distributing computer software that allows
you to try out a program before you purchase it. Programs dis-
tributed as shareware typically give you some period of time to use
the program and evaluate its usefulness to you. If the program
doesn't meet your needs, you're under no obligation to pay for it.
If you do find the program useful and wish to continue using it on
a regular basis, the shareware program's author usually requests
that you pay for the program by sending him or her a completed
registration form and payment. This is the approach Blue Sky
Software has taken in marketing OverView.
If you find OverView to be a useful addition to your software
library, please become a registered user by completing the enclosed
registration form and returning it along with the indicated
license/registration fee. I hope that you will agree that the $ 15
license fee is a small price to pay for the continued use of the
program. It requires a large investment to develop, market, and
support a product of this complexity. Your support in the form of
a license/registration fee will continue to make good software
available at low prices.
Quantity discounts are available to business, government, and other
organizations that wish to use OverView on multiple computer
systems. The topic QUANTITY DISCOUNTS, lists the quantity discount
rate structure.
OverView is also available at very special rates to organizations
who wish to use it in promotional campaigns. Write to Blue Sky
Software for information on using the program this way.
THE OVERVIEW LICENSE
You are granted a limited license to use and examine OverView on a
15 day trial basis to determine if OverView is suitable for your
needs. If you find OverView useful and continue to use it on a
regular basis, you should complete and return the registration form
along with the indicated license/registration fee.
3
OVERVIEW 2.20 DOCUMENTATION SHAREWARE CONSIDERATIONS
You are encouraged to make copies of OverView for the trial use of
other individuals and organizations, subject to the following
restrictions:
All OverView distribution files must be copied in unmodified
form, including the documentation, help, and executable image
files.
You may not include any other files with the distributed copy.
You may not request compensation of any sort for providing the
copy. This restriction does not apply to computer clubs and
user groups who distribute software to their members for a
nominal fee.
You may not distribute OverView with any other product or
service without written permission of the copyright holder.
OverView may be included on electronic bulletin board systems for
downloading by users of the bulletin board provided the above
restrictions are met.
THE OVERVIEW WARRANTY
OVERVIEW AND ALL ACCOMPANYING MATERIALS ARE PROVIDED "AS IS"
WITHOUT WARRANTY OF ANY KIND. THE ENTIRE RISK OF USING OVERVIEW IS
ASSUMED BY YOU.
Blue Sky Software and James Mathews make no warranty of any kind,
express or implied, including but not limited to any warranties of
merchantability and fitness for a particular purpose.
IN NO EVENT WILL BLUE SKY SOFTWARE OR JAMES MATHEWS BE LIABLE FOR
ANY DAMAGES WHATSOEVER (INCLUDING BUT NOT LIMITED TO DAMAGES FOR
LOSS OF BUSINESS PROFITS, LOSS OF SAVINGS, BUSINESS INTERRUPTION,
AND THE LIKE) ARISING OUT OF YOUR USE OR INABILITY TO USE THE
PROGRAM.
BY USING OVERVIEW, YOU AGREE TO THE ABOVE LIMITATIONS.
HOW TO REGISTER
If you use OverView on a regular basis, you should complete the
registration form at the end of this document and return it along
with the indicated license/registration fee. Registration gives
you the right to use the software as documented in the license.
There are three types of registrations available: 1) "registration
only", 2) "registration with disk", and 3) quantity. Registration
is required if OverView is used in a business, government, or other
organizational environment.
4
OVERVIEW 2.20 DOCUMENTATION SHAREWARE CONSIDERATIONS
The "registration only" fee of $ 15.00 establishes you as a
registered user of OverView. You will not receive any software
directly from Blue Sky Software, but you may from time to time,
receive notification when updated versions of OverView are
released.
The "registration with disk" fee of $ 20.00 establishes you as a
registered user of OverView and upon receipt of your registration/
license fee, you will be mailed a diskette containing the most
recent OverView version. Note that the version mailed to you may
be the same version you already have--although updated versions
will be released from time to time.
"Registration with disk" users also receive the current release of
OV286, a version of OverView specifically made for computers with
the Intel 80286 and 80386 microprocessors.
If you register once for any OverView version, you do not need to
register again for any subsequent release--a single registration
entitles you to use any new OverView releases without additional
license/registration fees.
The OverView registration form appears at the back of this
document. For your convenience, the same form is also contained in
the file REGISTER.FRM, which can easily be printed.
QUANTITY DISCOUNTS
Business, government, and other organizations that wish to use
OverView on multiple computer systems are eligible for a quantity
discount on the license/registration fee. The discount rate
structure is as follows:
QUANTITY FEE PER COPY DISCOUNT
1 - 5 $ 15.00 none.
6 - 10 $ 12.75 15 %
11 - 20 $ 11.25 25 %
21 - 50 $ 9.75 35 %
51 or more $ 7.50 50 %
In addition to quantity discounts, a site-license program is also
available. Write to Blue Sky Software if you are interested in
site-license information.

OVERVIEW 2.20 DOCUMENTATION INSTALLATION
SECTION 3: INSTALLATION
SYSTEM REQUIREMENTS
OverView requires an IBM Personal Computer, Personal System/2, or
compatible computer to work properly. In addition, version 2.0 or
greater of PC-DOS or MS-DOS is required.
OverView version 2.20 is "DESQview aware," meaning it can run in a
small window under Quarterdeck Office Systems' DESQview (tm) multi-
tasking program.
To improve display speed, OverView normally writes directly to the
video screen memory of your computer. OverView works well with the
IBM Monochrome Display Adapter (MDA), Color Graphics Adapter (CGA),
Enhanced Graphics Adapter (EGA), Video Graphics Array (VGA), and
compatibles. Other video adapters that can emulate either the MDA
or CGA should work properly.
This version of OverView requires approximately 95K of computer
memory to contain the program's executable code and common data.
Additional memory is allocated as required to contain the file
information for each open directory window and a copy buffer when
copying files. The file information memory can either be allocated
in conventional RAM or in LIM/EMS RAM if available on your system.
You can change OverView's total memory requirements by changing the
number of files allowed per directory window. The largest setting,
2515 files per window, requires 64K of additional memory (conven-
tional or EMS) per window. The default value of 1000 files per
window requires approximately 26K (32K if EMS) per window.
Since OverView is not a memory resident Terminate and Stay Resident
(TSR) program, the memory it uses is only required when you are
actually running the program. The advantage to using as little
conventional memory as possible is to allow any programs executed
from OverView as much memory as possible for their own purposes.
FILE SETUP
Installing OverView is a very simple process--there are only three
files required to run the program. They are OV.EXE (the program
itself), OV.HLP (the help file), and OV.CFG (the configuration
file). The OV.CFG file is optional in that OverView will create a
new OV.CFG file if it can't locate one when it starts up.
If your system has a DOS PATH command setup, simply copy these
three files into one of the directories identified in the PATH
command. If you have a hard disk system, but you haven't set up a
PATH command, you should read about it in the DOS manual or get
someone knowledgeable to help you set one up.
6
OVERVIEW 2.20 DOCUMENTATION INSTALLATION
Optionally, you can copy the OV.CFG and OV.HLP files into a
separate directory, and tell OverView where they reside by setting
the environment variable OVFILES to the name of the directory.
This has an advantage over using a PATH directory, because only the
single OVFILES directory needs to be searched when accessing the
OV.CFG or OV.HLP files. The following command in the AUTOEXEC.BAT
file informs OverView to look for its files in the directory C:\OV:
SET OVFILES=C:\OV
When OverView is started, it tries to read the OV.CFG configuration
file. This file contains the configuration options that you've
defined (for example, the display colors, the User Defined Key
values, and the Point-and-Go values). If the OVFILES environment
variable is defined, OverView expects to find the OV.CFG file
there. If OVFILES isn't defined, OverView looks in the current
directory; if OV.CFG isn't found there, the directories specified
by the PATH command are searched. If the file still can't be
located, a set of default parameters is used.
OverView must be able to locate the OV.HLP file when you ask for
on-line help. If OVFILES is defined, OverView looks for the OV.HLP
file in that directory. If OVFILES isn't defined, OverView looks
in the current directory and then the directories specified by the
PATH command. If the help file still can't be located, you'll be
asked to supply the location of OV.HLP.
If you are running a system with only floppy disks, it's recom-
mended that you copy OV.EXE, OV.CFG and OV.HLP to your system disk
(or disks if you have more than one system disk). The OV.HLP file
is not accessed unless you actually request help, so it could be
left off if you are short on disk space.
UPGRADING FROM EARLIER RELEASES
If you are upgrading to OverView version 2.20 from an earlier
release, you must replace all copies of the OV.EXE and OV.HLP files
with the 2.20 versions. If you're a new OverView user, you don't
need to replace any existing copies, and you can ignore the
remainder of this section.
OverView versions 2.10 and later use a different OV.CFG file format
than prior releases. If you don't want to keep any of your current
configuration settings (color selections, User Defined Keys, etc.),
you can replace all copies of OV.CFG with the distributed 2.20
version. In order to use pre 2.10 configuration settings with
version 2.20, you must run the included CVTCFG program to convert
older format OV.CFG files to the new format used by versions 2.10
and later.
OverView version 2.20 can use version 2.10 and later OV.CFG files
without the need for conversion.
7
OVERVIEW 2.20 DOCUMENTATION INSTALLATION
To convert your existing (pre 2.10) OV.CFG file, use the command
CVTCFG filename
where "filename" identifies the location of your OV.CFG file. For
example, the command
CVTCFG C:\BIN\OV.CFG
converts the OV.CFG file in the directory \BIN on drive C. If you
have more than one OV.CFG file (on different diskettes for
example), make sure you convert all of them.
OverView operates correctly even if the old OV.CFG file isn't
converted, but it will inform you that the configuration file is
obsolete and proceed to use a set of default values.
Starting with version 2.20, OverView displays directory tree names
in sorted order. If you've saved the directory tree structure in
the OV.DIR file, you'll need to do [Dir | Show Dir Tree | New] and
[... | Write] commands before your dir tree will be sorted.
For more information on the changes in version 2.20, refer to
APPENDIX A: SUMMARY OF NEW FEATURES.

OVERVIEW 2.20 DOCUMENTATION GETTING STARTED
SECTION 4: GETTING STARTED
OverView works in what we hope is an obvious and intuitive manner.
The best way to learn it is to use it. You can access OverView's
on-line help any time it is waiting for input by pressing the F1
function key.
You start OverView by typing OV and pressing Enter at a DOS command
prompt. OverView will display an initial start up screen while
reading the directory information of the files in the current drive
and directory. Press any key and OverView will show the main file
display.
There are four areas on the main file display; the menu bar, the
header area, the file name area, and the status line. The contents
and usage of the different screen areas are described below.
MENUS
The menu bar across the top line of the screen shows the top level
functions which OverView can perform. You select a function from
the menu bar by pressing the key that is the first letter of the
desired function. Depending on your computer's video equipment and
your video attribute/color setup, the first letter of the menu bar
choices may be displayed in a different color or otherwise high-
lighted to make them stand out visually.
In most cases, selecting a function from the menu bar results in a
"pull-down" submenu being opened. Submenus are a set of choices
that appear in a box under the corresponding top level option.
You select a submenu entry by either pressing the key that is high-
lighted in the submenu entry (not always the first letter), or by
using the up and down arrow keys to highlight the desired entry and
then pressing Enter. The Esc key can be used to exit a submenu
without selecting any of the choices.
In addition to the menus, many of OverView's most common functions
can be performed by the function keys and Alt key combinations.
Function and Alt key usage is described in the QUICK REFERENCE
section and in OverView's on-line help.
The menu and submenus are more difficult to describe than they are
to use. Simple experimentation quickly makes their usage obvious.
Following is an example showing the menu bar and an open submenu
(in this case, the Files submenu). Note, examples like the
following use the characters +, |, and - to show graphics because
some printers do not support the IBM PC graphics characters. When
displayed on your computer's screen, actual graphics characters
are used, making a much nicer display.

THE HEADER AREA
The header area at the top of the screen contains information about
the current disk drive, the current directory, and OverView
options.
The header section entitled "Volume" displays the volume label of
the current disk, the total storage capacity of the disk in bytes,
and the size of the remaining free space on the disk, also in
bytes. If the current disk does not have a volume label, the label
area is blank.
The header section entitled "Path" normally displays the complete
pathname of the current disk drive and directory. In either the
show-all or show-sub modes, the Path area displays the pathname of
the current file.
The header section labeled "Files" displays the number of files
listed in the file name area, the total size of those files in
bytes, the number of files tagged for group operations, and the
size of tagged files in bytes.
The final header section, "Selection", displays the selection
criteria used to pick which files are displayed in the file name
area. More information on the Selection area is provided in the
QUICK REFERENCE section.
Following is an example of the header area, edited to fit on this
page.

OVERVIEW 2.20 DOCUMENTATION GETTING STARTED
THE FILE NAME AREA
The file name area usually displays a sorted list of the file
names in the current directory. If there are more file names to
be shown than will fit on the screen at one time, you can use the
arrow keys or the PgUp, PgDn, Home, and End keys to display the
other file names.
Many of the OverView commands operate on the current file. The
current file is identified by being the only highlighted name in
the file name area. The four arrow keys and the PgUp, PgDn,
Home, and End keys can be used to select a different current
file. The highlighted bar over the file name is sometimes called
the current file pointer or just the file pointer.
The file name area can be split into multiple windows to display
different disk drives and/or directories on the screen at the
same time. Only one window is current at a time (sometimes
called the current window). Refer to the description of the
Window commands in the QUICK REFERENCE section for more infor-
mation on windows.
THE STATUS LINE
The status line appears along the bottom line of your computer's
screen. The status line is divided into 3 segments. The first
segment tells you what OverView is doing and when it is ready for
your input. The second segment simply reminds you that you can
press the F1 function key for on-line help. The third segment
shows whether or not the DOS verify mode is set on or off (refer
to your DOS documentation for a description of verify flag).
Following is an edited example of the file name area (with two
windows displayed) and the status line.

OVERVIEW 2.20 DOCUMENTATION QUICK REFERENCE
SECTION 5: QUICK REFERENCE
This section is not a complete description of all OverView
features and functions. Instead this section focuses on the more
advanced features of the program and some topics that can help
you get the most from it. Until you become familiar with
OverView, you should look over this section from time to time
for ideas on other ways to use its features.
The on-line help facility should be used to supplement the infor-
mation presented in this section. You can get help any time the
program is waiting for input by hitting the F1 key.
ALT KEY USAGE
OverView has a number of Alt-key combinations that are short-cuts
to many of the most common functions. Entering one of the
following Alt-key combinations executes the corresponding menu
entry, without traveling through the menus. Menu entries that
have Alt-key short-cuts display the short-cut at the right edge
of the menu line.
Alt-A Files | Set File Attributes | Current File
Alt-B Files | Set File Attributes | Tagged Files
Alt-C Files | Copy file(s) | Current File
Alt-K Files | Copy file(s) | Tagged Files
Alt-E Files | Erase file(s) | Current File

Alt-P Other | Setup Parameters | Point and Go Setup
Alt-U Other | Setup Parameters | User Defined Keys
Alt-D Xecute | Current File
Alt-X Xecute | DOS Command
Alt-Q Quit
The Alt-Fn (function key) combinations are called User Defined
Keys and are described in the topic of the same name.

OVERVIEW 2.20 DOCUMENTATION QUICK REFERENCE
COMMAND LINE PARAMETERS
The usual way to start up OverView is to simply type OV and press
Enter at a DOS command prompt. However, the following optional
parameters can be specified on the command line to modify
OverView's behavior during a given run:
/C or -C Instructs OverView to only use conventional memory,
even if LIM/EMS memory is available and the [Use EMS
(if available)] option is enabled.
/E or -E Allows use of LIM/EMS memory even if [Use EMS (if
available)] option is disabled.
/F or -F Do not perform video "snow" checking even if the
[Video Snow Checking] option is set.
/S or -S Perform video snow checking even if the [Video Snow
Checking] option is disabled.
/M or -M Indicates that the following parameter is a file name
mask. See below for an example of a file name mask.
The OverView command line can contain the name of the initial
directory to display when OverView is started. The following
command:
OV C:\LETTERS
starts OverView with the directory C:\LETTERS displayed, regard-
less of what the current directory was when the command was
entered. Specifying a directory name on the command line is
equivalent to starting OverView without a directory name, and
then using the Alt-L or [Dir | Login New Directory] command to
switch to the desired directory.
A file name mask to display specific file names can also be
entered on the command line, but only immediately after a /M
parameter. Supplying a file name mask on the command line works
just as if the mask was specified with the [Other | Selection
Criteria | File Name Mask] command. For example, the command
line:
OV /M *.DBF
invokes OverView and tells it to only display files that have an
extension of .DBF
The file name mask must follow the /M parameter on the command
line. Several parameters can be entered on the same command
line. For example:
OV/S/C/M *.COM D:\BIN

OVERVIEW 2.20 DOCUMENTATION QUICK REFERENCE
starts OverView with video snow checking enabled (/S), EMS usage
disabled (/C), and only files with the extension .COM in the
directory D:\BIN displayed.
Refer to the topics USING LIM/EMS MEMORY and VIDEO SNOW CHECKING
for more information on EMS memory and video snow checking.
CONTROL KEY USAGE
OverView allows several Control-key combinations to be used in
addition to the arrow and keypad keys. The Control-keys add a
WordStar (tm) like interface to OverView. The sequence ^R means
to hold down the Ctrl key and simultaneously press the 'R' key.
^R - Same as PgUp ^G - Same as Del
^C - Same as PgDn ^V - Same as Ins
^H - Same as backspace
^W, ^E - Same as up arrow ^M - Same as Enter
^Z, ^X - Same as down arrow
^T - Tag/untag current
^A, ^S - Same as left arrow file
^D, ^F - Same as right arrow
CUSTOM SCREEN COLORS
The [Other | Setup Parameters | Screen Colors] command allows you
to customize the video attributes OverView uses to display var-
ious types of information. On a color display monitor, the video
attributes determine which colors are displayed. On a monochrome
monitor, the attributes select display options such as under-
lined, inverse video, and intensity.
You can specify video attributes for ten different types of
displayed text. They are: Normal text, Highlighted text, Window
text, Highlighted window text, Heading text, Background text,
Tagged file name text, Menu text, Highlighted menu text, and
Selected menu text. The easiest way to determine what the
different types of text are is by try changing the colors and
observing the results.
When you select the [... | Screen Colors] command, the display
shows the types of text that can be selected, the attribute
combinations allowed, and short directions. The PgUp and PgDn
keys on the numeric keypad select the type of text to define,
while the arrow keys select the particular display attribute for
that type of text. The current type of text and the current
attribute are always indicated by > TEXT < characters.

14
OVERVIEW 2.20 DOCUMENTATION QUICK REFERENCE
When changing video attributes, three choices are available from
the menu bar; Accept, Reset, and Quit. Use the [Accept] option
to begin using the color combination you've selected. If you've
selected a set of attributes you don't like, you can use the
[Quit] command to return to the previous attribute settings.
With the [Reset] command, you can restore the default (permanent)
settings even if you've accepted other attributes. [Reset]
restores the last settings that were written to the OV.CFG file.
THE DIR TREE
When the directory tree is displayed by Alt-T or the [Dir | Show
Dir Tree] command, a graphic tree somewhat like the following is
shown:
C:\ ---------+ BIN
+ CATDISK
+ COMM --------+ PCP
| + PROCOMM
+ GRAPHIC -----+ MAC
| + PAINT
+ INCLUDE ------ SYS
+ LIB
+ SRC ---------- OV
+ WRITE -------+ ARTICLES
+ WS
The tree represents the structure of the directories on the
current disk drive. Each column to the right indicates another
subdirectory. The directories described by the tree above are:
C:\
C:\BIN
C:\CATDISK
C:\COMM
C:\COMM\PCP
C:\COMM\PROCOMM
C:\GRAPHIC
C:\GRAPHIC\MAC
C:\GRAPHIC\PAINT
...
and so on.
The current directory is shown under a highlighted bar (called
the dir pointer). You can switch to another directory by using
the up, down, right, left arrow keys to highlight the new
directory. In addition, the Home key moves to the top level or
"root" directory and the End key moves to the lowest rightmost
directory. OverView does not actually switch (or "login") to the
new directory until you press the Enter key or select the [Login]
option from the directory tree menu bar.
15
OVERVIEW 2.20 DOCUMENTATION QUICK REFERENCE
As you move the dir pointer around the tree, the currently logged
in directory remains displayed in a different color/video
attribute. This is the directory to which OverView returns if
you press the Esc key or select the [Quit] option from the
directory tree menu bar, regardless of the dir pointer location.
With the directory tree [Write] command, you can save the direc-
tory tree information in a single disk file (named OV.DIR in the
top level directory of the current disk). When you bring up the
directory tree display, OverView checks for this disk file--if it
exists, the directory tree information is read from the file
instead of searching the disk for directories. This results in a
much faster tree display.
If you change you disk's directory structure outside of OverView,
you can force a rescan the entire disk for directories (instead
of just reading the OV.DIR file) by using the directory tree
[New] command. This informs OverView of the changes you've made
to directories since the last time the disk was scanned.
The directory tree [Mkdir] command (similar to the DOS command of
the same name) "makes" a new subdirectory "under" the dir
pointer. For example, if you select the [Mkdir] command while
the dir pointer is on the directory C:\123\SALES, and you enter
"JOURNAL" as the new subdirectory name, OverView creates the
directory C:\123\SALES\JOURNAL. New directories created by
[Mkdir] immediately appear in the graphic tree display.
The directory tree [Rmdir] command (also similar to the DOS
command of the same name) deletes or "removes" the subdirectory
under the dir pointer. Selecting [Rmdir] when the dir pointer
was on the directory D:\FORMS\LETTERS\SUPPORT will delete the
SUPPORT directory, provided the following conditions are meet:
- You can't delete the directory you're currently logged in to
(the current directory).
- You can't delete the top level (root) directory of a disk.
- You can't delete a directory that contains any files and/or
other directories. If you want to delete a directory that
contains files, delete the files first using the [Files |
Erase File(s)] command.
There are two directory tree options that are useful in conjunc-
tion with the [Write] command. Both options are related to
writing the directory tree file to disk whenever changes are made
in the disk's directory structure. Keeping the file synchronized
with the actual directory structure is important since OverView
does not scan the disk for directories if the OV.DIR file exits
(unless you use the [New] command as noted above).
16
OVERVIEW 2.20 DOCUMENTATION QUICK REFERENCE
The first option, [Other | Setup Parameters | Directory Tree
Options | Select Drives to Always Write] allows you to specify a
set of disk drives which are to automatically have the OV.DIR
file rewritten whenever you exit the directory tree and there
were directories created or deleted. A useful application of
this option is to specify all your computer's hard disks. The
drives should be specified as single letters, with or without
colons (:) and spaces.
The second option, [... | Prompt to Write when changes] causes
OverView to ask you if the OV.DIR file should be written when
changes have been made in the directory structure. This option
is useful when you may or may not want to write to the disk.
If neither option is specified, OverView does not write the
directory tree file to disk unless you explicitly use the [Write]
command to do so.
DOS COMMAND MACROS
A set of command line "macros" are available for use wherever
OverView accepts input of a DOS command ([Xecute | Current File],
[Xecute | DOS Command], User Defined Keys, and Point-and-Go com-
mands). Before executing the DOS command, OverView replaces the
macro with its value. The supported macros are:
$C - The current file name, with extension.
$D - The current drive letter, without a trailing colon (:).
$F - The full pathname of the current file, including drive,
directory, and file name (with extension).
$P - The directory pathname for the current or tagged file,
without a trailing backslash (unless the current directory
is the root and a \ does not follow the $P macro).
$T - The first or next tagged file name, with extension. When
$T appears in a command line, OverView executes the
command once for each tagged file.
$XC - The current file name, without its extension or trailing
period.
$XT - The first or next tagged file name, without its extension
or trailing period. Like $T, $XT causes the command to
be run once for each tagged file name.
Macro examples:
PRINT $C
Runs the DOS PRINT command on the current file. If the file
pointer was on the file OV.DOC, the command is executed as:
PRINT OV.DOC
17
OVERVIEW 2.20 DOCUMENTATION QUICK REFERENCE
ARC A OV210 $T
Runs the ARC program once for each tagged file. If the
files OV.CFG, OV.DOC, OV.EXE, and OV.HLP were tagged, the
following commands are executed:
ARC A OV210 OV.CFG
ARC A OV210 OV.DOC
ARC A OV210 OV.EXE
ARC A OV210 OV.HLP
When executing a DOS command in the Show-all or Show-sub modes
(multiple directories displayed in a single file name window),
use the $F or $P macros to ensure the command looks for the file
in the proper directory. Without the $F or $P, the command will
most likely assume the file is in the current directory, while it
may in fact be in a different directory. The command
FIND "silver" $T
tries to find the string "silver" in all tagged files, but will
not be able to search those files that are not in the current
directory. The command
FIND "silver" $P\$T
searches all tagged files using the file's complete pathname
(including files not in the current directory).
To pass a macro name to DOS without being expanded, use two $'s.
The command
FLARP *.C $$P /DI
is executed as:
FLARP *.C $P /DI
The macro names can be entered in upper or lower case, thus $C is
the same as $c.
Entering a $T or $XT macro on a command line causes OverView to
execute the command once for each tagged file in the current
window. If you have a ram disk on your computer system, you can
speed up such operations by putting a copy of the DOS COMMAND.COM
file on the ram disk and pointing the COMSPEC environment vari-
able to it. For example, if your system has a ram disk as drive
D: the following commands in the AUTOEXEC.BAT would copy the
COMMAND.COM file and setup the COMSPEC environment variable:
COPY C:\COMMAND.COM D:
SET COMSPEC=D:\COMMAND.COM
18
OVERVIEW 2.20 DOCUMENTATION QUICK REFERENCE
EDITING RESPONSES
When you are prompted for a response in a pop-up window (for
example, when logging in to a new directory or when entering a
DOS command to execute), the response can be edited with the
Home, End, Ins, Del, backspace, left arrow, and right arrow keys
up until the time you press the Enter key to end the input.
The Home and End keys move the cursor to the left and right ends
of the response, respectively. The Ins key turns insert mode on
and off, allowing existing data to be overtyped (when off) or new
data inserted (when on). The cursor is made larger when insert
mode is turned on. The Del key deletes the character at the
cursor position, while the backspace key deletes the character
just to the left of the cursor. The left and right arrow keys
simply move the cursor in the corresponding direction.
The up and down arrow keys can also be used when entering a
response. OverView keeps the last 10 responses entered, and
recalls the next oldest response each time the up arrow key is
pressed. The recalled response can be edited or accepted (by
pressing Enter) just as if it had been typed in again. If you go
past the response you wanted with the up arrow key, the down
arrow can be used to recall the more recent responses.
Finally, the PgUp and PgDn keys also effect the entry and editing
of responses. Pressing the PgUp or PgDn key when entering a
response inserts the name of the directory displayed in the file
name window above or below the current window, respectively.
Each time the PgUp or PgDn key is pressed, the next higher or
next lower window's directory name is inserted. This is useful
when performing operations such as copying files or logging in to
another directory.
THE ESC KEY
The Esc key quits or aborts whatever operation OverView is
currently performing. The exact effect of pressing Esc depends
on the operation being performed.
At the highest level, the Esc key returns to the normal file name
display from viewing a file, viewing the directory tree, setting
color selections, and the on-line help facility.
Many of OverView's submenus do not have a selection to quit or
exit without performing a function. The Esc key does this by
closing the last opened submenu. When multiple submenus are
open, they can be closed in reverse order by pressing Esc once
for each submenu.
The Esc key also escapes from most pop-up window prompts. For
example, selecting the [Dir | Login New Directory] command pops
up a window asking which directory to log in. If you decide not
19
OVERVIEW 2.20 DOCUMENTATION QUICK REFERENCE
to switch to another directory, just press the Esc key and the
window will disappear.
EXTRA FILE INFORMATION
OverView can display three levels of detail about files stored on
disk. The lowest level of detail shows only file names, and is
illustrated below:
ANSI.SYS COMMAND.COM DRIVER.SYS JDISK.SYS QEMM.SYS
AUTOEXEC.BAT CONFIG.NEW DUET\ LIB\ RES86.COM
BATCH\ CONFIG.OLD DV\ MOUSE.SYS SRC\
At the lowest level of detail, OverView is able to show five
columns of file names per window.
The second level of detail displays full information on each
file. In addition to the file's name; its size, creation or
modification date and time, and attributes are shown. An example
of the full file information display is shown below:
NAME USED ALLOCATED DATE TIME R H S A DIR
ANSI.SYS 4963 6144 7/20/87 1:00:00 pm . . . .
AUTOEXEC.BAT 1134 2048 11/27/87 8:01:26 pm . . . .
BATCH\ <DIR> <DIR> 11/21/87 5:31:52 pm . . . . DIR
BIN\ <DIR> <DIR> 11/21/87 5:16:48 pm . . . . DIR
IBMBIO.COM 16557 18432 7/20/87 1:00:00 pm R H S .
IBMDOS.COM 28464 28672 7/20/87 1:00:00 pm R H S .
Each file (except for directories) shows two file sizes, USED and
ALLOCATED. Due to the manner in which DOS stores files on disk,
a file often requires more space than it actually uses. The file
size reported in the USED column is the amount of useful data
actually in the file. The size reported in the ALLOCATED column
is the amount of space allocated or reserved for the file. The
allocated (but unused) space is not available for other files to
use.
A file's attributes are shown as a single character if the
attribute is on, or a period if the attribute is off (R -
Read/Only, H - Hidden, S - System, and A - Archive). The
Directory attribute is shown by the characters DIR.
When full file information is being displayed, only one column of
file names can be shown per window.
The third level of detail displays some, but not all, of the
information per file. The fields shown are: name, file size,
and creation or modification date and time. The allocated size
and file attributes are not shown, allowing two columns of file
names to be shown per window. An example is shown below (only
one file per row will fit on the printed page):

AUTOEXEC.BAT 1208 3/24/88 1:40p
BATCH\ <DIR> 2/14/88 11:03p
The level of detail displayed is changed with the Alt-I or [Files
| Extra File Info] command. A default level of detail can be set
with the [Other | Setup Parameters | Startup Defaults | Extra
File Info (1 col)] and [ ... (2 col)] options.
FILE LIMITS
OverView allows you to select the maximum number of files that
can be displayed in a file name window. The number of files per
window directly corresponds to the amount of your computer's
memory required to hold file information. The smallest number
allowed is 100, while the maximum is 2515. Approximately 64K of
memory is used to hold file information when the maximum value of
2515 is selected. Having four maximum sized windows open at once
would require 256K of memory, just to hold file information.
If you want to minimize the amount of memory that OverView itself
uses, select a value for the number of files per window that is
just large enough to hold all the files in one or your typical
directories. Minimizing OverView's memory usage allows more
memory for any programs executed from within OverView.
The number of files per window is set with the [Other | Setup
Parameters | # Files per Window] command. Changing this value
does not effect any file name windows that are already open, only
windows opened afterwards (via F7 or the [Window | Open] command),
will have the new value.
The number of files per window can be increased on a temporary
basis by selecting the new value and then responding with an N to
the "Write Changed Parameters to Disk (y/N):" prompt.
OverView's conventional memory requirement can be greatly reduced
if your computer has LIM/EMS memory available to hold file infor-
mation. See the topic USING LIM/EMS MEMORY for more information.
FILE SELECTION ATTRIBUTES
File Selection Attributes allow you to work with a select group
of disk files, based on the DOS file attributes that the files
themselves have. The following attributes can be used for file
selection:
Normal - Selects files which have none of the following
attributes set. This is not really a DOS file
attribute, but it's useful to treat it as one.
21
OVERVIEW 2.20 DOCUMENTATION QUICK REFERENCE
Archive - Selects files which have the Archive attribute
set. DOS sets the Archive attribute when a file
is created or modified.
Dir - Selects files which are subdirectories.
Hidden - Selects files which have the Hidden attribute set.
Read/Only - Selects files which have the Read/Only attribute
set.
System - Selects files which have the System attribute set.
As distributed, OverView's default file selection attributes are
N (Normal), R (Read/Only), A (Archive), and D (Dir). This means
that only files with normal attributes (that is no attributes),
the Read/Only attribute, the Archive attribute, or the Directory
attribute are displayed.
Selection attributes work by only displaying files that have one
or more matching attributes. A file which does not have any
matching attributes is not displayed. The current file selection
attributes are shown in the header "Selection" area. The dis-
played attributes are abbreviated to their first letter.
There are two commands that set file selections attributes;
[Other | Selection Criteria | by Attribute] and [Other | Setup
Parameters | Startup Defaults | Selection Attribs].
The [Other | Selection Criteria | by Attribute] command sets the
selection attributes for the current file name window. This
command allows different windows to be given different selection
attributes, thereby displaying different collections of files.
When this command is used, OverView rereads the current window's
directory (or directories if show-all or show-sub mode is active)
and only displays those files which match the new attributes.
As an example, you can display all modified files on your disk
(and only the modified files) by using [Other | Selection
Criteria | by Attribute] to turn off all attributes except
Archive. Then use [Dir | Show All Dirs] to read all directories
on the disk. Only the modified files (those with the Archive
attribute set) will be displayed.
The other selection attribute command, [Other | Setup Parameters
| Startup Defaults | Selection Attribs] sets OverView's default
selection attributes. These are the initial attributes used
every time you start OverView. OverView is distributed with the
Hidden and System attributes turned off since files with these
attributes are not typically manipulated by users. If you always
like to see every file in any given directory, change the default
attributes to include Hidden and System files.
22
OVERVIEW 2.20 DOCUMENTATION QUICK REFERENCE
FIND FILE NAME
The Find File Name command moves the file pointer to the first
file name in the current window that matches the characters you
specify. To search for (find) a given file name in the current
window, first press the equals (=) key. Each character typed
after the '=' key further defines the file name to find. For
example, typing '=O' moves the file pointer to the first file in
the window that starts with the letter 'O'. If you then type the
letter 'V', the file pointer will move to the first file name
starting with 'OV'.
If you type a character for which there is no matching file name,
a beep will sound and the file pointer will not move. You can
change the name to search for by using the Backspace key, all the
way back to the '=' key. The status line at the bottom of the
screen contains the current file name search string and brief
instructions after typing '='.
The Find File Name command can be terminated by the Esc key and
most other non alpha-numeric keys and commands. The sequence
=OV Ctrl-T moves the file pointer to the first file name starting
with OV and tags that file. It is not necessary to press Esc
before Ctrl-T.
It's important to realize that the Find File Name command does
not search the disk for a given file, it only searches the list
of names in the current directory window. If the file name is
not in the window, Find File Name will not find it. To use this
command to search for a specific file somewhere on disk, use it
in conjunction with the [Dir | Show All Dirs] command to search
all file names on the disk.
FUNCTION KEY USAGE
OverView uses the function keys on the keyboard to execute
several common functions with a single key. The function key
usage is:
F1 - Get Help
F2 - Tag/Untag the current file (toggles current tag state)
F3 - Login to the parent directory
F4 - Login to the subdirectory under the file pointer
F5 - Goto the next tagged file (next find in VIEW)
F6 - Goto the previous tagged file (prev find in VIEW)
F7 - Open another file name display window
F8 - Close the current file name display window
23
OVERVIEW 2.20 DOCUMENTATION QUICK REFERENCE
F9 - Goto the next file name display window
F10 - Goto the previous file name display window
The Alt-Fn (function key) combinations are called User Defined
Keys and are described in the topic of the same name.
INTERRUPTING TAGGED FILE OPERATIONS
When performing an operation on all tagged files (copy tagged,
rename tagged, erase tagged, etc.), the Esc, Ctrl-U, Ctrl-C, or
Ctrl-Break keys can be used to interrupt the process. Striking
one of these keys during a tagged file operation causes the
message "Interrupt?" to be displayed. Respond Y to stop the
operation, N to continue.
Interrupting a tagged file operation doesn't restore files that
have already been processed, but it can keep further files from
being modified.
POINT-AND-GO
OverView's Point-and-Go facility provides the ability to operate
on files with DOS commands or other programs simply by pointing
at the file name and "executing" the file. Whenever OverView
executes a file, it looks at the file's extension to determine
what processing is required. If the extension is COM, EXE, or
BAT, the file is treated as an executable program (COM or EXE) or
as a batch file of DOS commands (BAT). If the file has an exten-
sion other than COM, EXE, or BAT, OverView searches a table of
file extensions and commands to determine how to process the
file. Instead of executing the file itself, OverView performs
one or more DOS commands defined for files with matching exten-
sions.
The Point-and-Go commands are most useful when combined with
OverView's command line macros. These macros allow information
such as the current drive, directory, and/or file name to be
added to the command before it's executed. See the topic DOS
COMMAND MACROS for a complete description of the available
macros.
As with User Defined Keys and the [Xecute] commands, you can
specify multiple DOS commands to be executed in a Point-and-Go
entry by separating the commands with '^' characters. The
following example shows three DOS commands that could be given in
a Point-and-Go entry. All three commands would be executed, in
left to right order, when a file with a matching extension is
"executed."
del $xc.old^rename $xc.bak $xc.old^ws $c
24
OVERVIEW 2.20 DOCUMENTATION QUICK REFERENCE
As an example of how to setup the Point-and-Go entries, consider
an entry with an extension of DOC and a command of WS $C. When-
ever you enter Alt-X (short-cut for [Xecute | Current File]) with
the file pointer over a DOC file, OverView executes the WS
program with the current file name as a parameter. Alt-X with
the file pointer on the file OV.DOC would execute the command
WS OV.DOC
while Alt-X on the file DC_TRIP.DOC would execute the command
WS DC_TRIP.DOC
The Point-and-Go table can hold up to 10 extension/command
entries. You create and modify the entries with the [Other |
Setup Parameters | Point and Go Setup] command. Each entry can
specify from 1 to 3 different extensions. When entering multiple
extensions, make sure to separate them with a single space. The
following example shows how a couple of Point-and-Go entries
might look:
NUM EXT(s) COMMAND PROTOTYPE PAUSE READ
1 doc ws $c N N
2 c asm txt edlin $f N N
3 ltr del $xc.bak^ws $c N N
4
Entry number 1 is the WS $C example presented above. Entry
number 2 shows a command for use with three different extensions
(C, ASM, and TXT). Entry 3 shows two commands being executed for
LTR files, while entry 4 is undefined.
For each Point-and-Go entry, you can define whether or not
OverView pauses and/or rereads the current directory after
executing the DOS command(s). If you enter Y (for yes) in a
entry's PAUSE column, OverView waits for you to press a key after
running the command(s). A N (for no) in the PAUSE column causes
OverView's screen to be redisplayed as soon as the command(s)
finish. Entering Y for PAUSE allows you to view any output the
command(s) leave on the screen before OverView redisplays its own
screen.
Entering Y in the READ column of an entry tells OverView to
reread the current directory when the command(s) finish. A N
value will not reread the directory. Y should most likely be
specified if the command(s) create or delete files, or if they
change the current directory. Note however that rereading the
directory has the disadvantage of forgetting which files were
tagged before the command(s) were executed.
25
OVERVIEW 2.20 DOCUMENTATION QUICK REFERENCE
SHOW-ALL AND SHOW-SUB MODES
Normally OverView displays the contents of a single directory in
each file name window. This mode of operation matches the way
most people organize their data on disk--related files are put
together in the same directory. At times however, it's more
convenient to see all the files in a given set of directories, or
even all the files on a disk.
The [Dir | Show All Dirs] and [Dir | Show Sub Dirs] commands do
just that. [Show All Dirs] displays all files on the current
disk (called show-all mode) and the [Show Sub Dirs] command
displays all files in the current directory and any directories
under the current directory (called show-sub mode).
So that you can tell in which directory a given file resides when
show-all or show-sub mode is active, the Path section of the
header displays the directory name of the current file. As you
move the file pointer through the displayed file names, the Path
changes to show the location of the current file. Normally all
the file names displayed in a window would be in the same direc-
tory, so the Path section wouldn't change from file to file.
Selecting [Show All Dirs] or [Show Sub Dirs] a second time turns
off the corresponding mode and restores the display of the files
in the current directory.
You can use these commands in conjunction with the selection mask
and/or selection attributes to limit the files displayed. For
example, a selection mask of *.EXE combined with [Show All Dirs]
displays all EXE files on the current disk.
Show-all and show-sub modes are one OverView's most powerful
features. In these modes, you can work with all the files on the
disk (or in a given directory tree) just as easily as you could
with the files in a single directory.
Some examples of show-all/sub uses are:
1) Erase all the .BAK files on drive C.
- Select all files on drive C (Dir | Show All Dirs).
- Tag all files with the extension .BAK (Tag/Untag | by Name).
- Erase all tagged files (Files | Erase File(s) | Tagged Files
or Alt-Y).
2) Turn off the Archive attribute of selected files so the DOS
BACKUP program will not copy them to disk.
- Select all files (Dir | Show All Dirs).
- Tag all modified files (Tag/Untag | Modified).
- Display only the tagged files (Tag/Unatg | Select Tagged).
- Untag (F2 key) the files which are to be backed up - leaving
only modified files not to backed up still tagged.
26
OVERVIEW 2.20 DOCUMENTATION QUICK REFERENCE
- Turn off the Archive attribute of the tagged files (Files |
Set File Attributes | Tagged Files or Alt-B).
SUBDIRECTORIES
DOS allows subdirectories to be given names just like any other
type of file. When looking at a list of file names, it's easy to
forget which names represent files and which names are actually
subdirectories. To make the distinction clear, OverView displays
directory names with a backslash character (\) following the
name. The following list shows several file and directory names
as they would be displayed by OverView:
ANSI.SYS COMMAND.COM DRIVER.SYS JDISK QEMM.SYS
AUTOEXEC.BAT CONFIG.SYS DUET\ LIB\ SRC\
BATCH\ CONFIG.OLD DV\ NOTES
In addition to the [Dir | Login New Drive] and [Dir | Login New
Directory] commands, the F3 and F4 function keys can also be used
to change directories. The F3 key will login to the parent of
the current directory, up to the top level root directory on the
current disk. The F4 key will login to the subdirectory under
the file pointer.
TERMINATE AND STAY RESIDENT UTILITIES AND OVERVIEW
Terminate and Stay Resident (TSR) programs load into memory and
remain there when executed. You should be careful to avoid
loading TSR routines from OverView since the TSRs would placed
above OverView in memory. When you exit OverView, an unused
"hole" would be left in memory where OverView used to reside.
This hole in the computer's memory would generally cut down on
the amount of memory available to other programs executed after
quitting OverView. This is true not only of OverView, but many
other programs that also give you access to DOS.
One common DOS command, the PRINT command, is a TSR utility that
remains in memory after being loaded the first time. If you're
going to use the PRINT command from within OverView, make sure
that PRINT is used at least once before starting OverView. The
following command could be added to your AUTOEXEC.BAT startup
file to load the resident portion of the PRINT command whenever
the computer is turned on or restarted.
PRINT /D:PRN >NUL:
The >NUL: on the command line simply keeps a couple of messages
from the PRINT program from appearing on the screen. This
command should work in DOS versions 3.1 and above. Refer to your
DOS manual for more information on the PRINT /D command option.

UPDATE TARGET DIRECTORY
When maintaining backup copies of files, or working with the same
set of files on multiple computers, it's often necessary to
update the your files so that all copies of the same file are
indeed the same version.
OverView's [Dir | Update Target Directory] command provides a
convenient way to synchronize the files in different directories
or disk drives. Two directories are used by the [Update Target
Directory] command; the source and the target. OverView selec-
tively copies files from the source to the target, so that the
target directory contains the same files as the source.
What makes this command more convenient than a simple copy is
that it only copies the files in the source directory that were
created or modified more recently than the corresponding files in
the target directory.
The source directory is always the current directory when the
[Update Target Directory] command is executed. OverView prompts
you to enter the name of the target directory before copying any
files.
The [Dir | Update existing files only] option modifies the
behavior of the [Update Target Directory] command. When this
option is off, all files in the source directory are checked
against the target, and are copied if more recent or if they
don't exist in the target directory. When the [Update existing
files only] option is on, only files already in the target
directory will be updated--files in the source directory but not
in the target will not be copied.
Because OverView uses the creation/modification date and time to
determine if the files are the same or not, it's important that
the date and times be accurate for this command to work properly.
If your computer system doesn't have a real time clock, make sure
the date and time is set correctly whenever the computer is
turned on or restarted.
USER DEFINED KEYS
OverView provides the ability to execute user defined commands at
the touch of a key. There are 10 User Defined Keys available,
numbered 1 through 10. A particular User Defined Key is executed
by pressing an Alt-Function key sequence; Alt-F1 executes User
Defined Key number 1, Alt-F2 executes User Defined Key number 2,
and so forth.
User Defined Keys are created and modified with the [Other |
Setup Parameters | User Defined Keys] command. The following
sample entries show how User Defined Keys are entered.
28
OVERVIEW 2.20 DOCUMENTATION QUICK REFERENCE
NUM KEY COMMAND PROTOTYPE PAUSE READ
1 A-F1 edlin $f N N
2 A-F2 arc v $f Y N
3 A-F3 chkdsk $d: Y N
The first entry (invoked by the Alt-F1 sequence) runs the program
EDLIN with the name of the current file as a parameter. Assuming
EDLIN is a text editor, you could edit any text file by moving
the file pointer to the file's name and pressing Alt-F1.
The second entry shown above runs the program ARC with two
parameters; the letter V and the name of the current file.
ARC is a popular program for maintaining ARChive files. Moving
the file pointer to a .ARC file and pressing Alt-F2 would list
the contents of the .ARC file.
The third entry shown above runs the DOS CHKDSK command with the
current drive letter as a parameter.
As with Point-and-Go entries and the [Xecute] commands, you can
specify multiple DOS commands to be executed by a User Defined
Key. Each command must be separated from the others by the '^'
character. The following example shows two DOS commands that
could be executed by a User Defined Key:
del $xc.bak^edwin $c
For each User Defined Key, you can specify whether or not
OverView pauses and/or rereads the current directory after
executing the command(s). If you enter Y (for yes) in a
command's PAUSE column, OverView waits for you to press a key
after running the command(s). A N (for no) in the PAUSE column
causes OverView's screen to be redisplayed as soon as the
command(s) finish. Entering Y for PAUSE allows you to view any
output the command(s) leave on the screen before OverView
redisplays its own screen.
Entering Y in the READ column of an entry tells OverView to
reread the current directory when the command(s) finish. A N
value will not reread the directory. Y should most likely be
specified if the command(s) create or delete files, or if they
change the current directory. Note however that rereading the
directory has the disadvantage of forgetting which files were
tagged before the command(s) were executed.
USING LIM/EMS MEMORY
OverView can make use of two different types of memory in your
computer system--conventional and expanded. Conventional memory
is that part of memory used and controlled by DOS. There is
normally somewhere between 128K and 640K of conventional memory
available in an IBM PC or compatible system.
29
OVERVIEW 2.20 DOCUMENTATION QUICK REFERENCE
The Lotus/Intel/Microsoft (LIM) Expanded Memory Specification
(EMS) is a hardware and software system that provides extra
(expanded) memory to programs that know how to use it. If your
computer system has EMS compatible memory installed, OverView can
use this memory to store file names and other file data. Allow-
ing OverView to utilize EMS memory is advantageous because it
leaves additional conventional memory available to execute DOS
commands and other programs from OverView.
The [Other | Setup Parameters | Other Options | Use EMS (if
available)] option enables or disables OverView's use of LIM/EMS
memory. If your computer system does not have LIM/EMS memory
installed, this option has no effect as OverView will then use
conventional memory anyway. The [... | Use EMS (if available)]
option is turned on when a check mark is displayed in front of
the option--it's off when a not sign precedes the option.
You can also enable or disable OverView's use of EMS memory with
the /C and /E command line parameters. Refer the the topic
COMMAND LINE PARAMETERS for more information.
As distributed, the [Use EMS (if available)] option is on to
allow OverView's use of EMS memory--if EMS memory isn't avail-
able, conventional memory will be used anyway.
VIDEO SNOW CHECKING
The [Other | Setup Parameters | Other Options | Video Snow
Checking] option allows for faster screen updates on computer
systems that do not make "snow" when writing directly to video
memory. This option is only useful for some systems with color
displays--monochrome displays do not make "snow" and OverView
knows not to check for snow when using a monochrome adapter.
Disabling "snow" checking can significantly speed up screen
updates. If you are not sure if your color display adapter makes
snow or not, try disabling OverView's snow checking. It will
quickly be obvious if you need to re-enable the snow checking.
Snow checking is enabled when a check mark is displayed before
the [... | Video Snow Checking] option. Snow checking is dis-
abled when a not sign is displayed.
You can also enable or disable snow checking with the /F and /S
command line parameters. Refer the the topic COMMAND LINE
PARAMETERS for more information.
As distributed, video snow checking is enabled.

OVERVIEW 2.20 DOCUMENTATION QUICK REFERENCE
WINDOW COMMANDS
OverView can display from 1 to 6 file name windows on the screen
at a time. Each window is independent of the others and can
display the same or a different drive/directory. File name
windows are opened, closed, and switched with the [Windows]
command.
When you start OverView, it initially has one file name window
open, displaying the contents of the current directory. As you
open and close additional windows with the [Windows | Open] and
[Windows | Close] commands, the size of the windows will be
adjusted so that all open windows have an equal amount of screen
space. The F7 and F8 keys are short-cuts for opening and closing
windows, respectively.
Only one of the open windows can contain the file pointer at a
time; this is called the current window. The Path, Files, and
Selection sections of the header area at the top of the screen
always display information about the current window. As you move
the file pointer from window to window with the [Window | Next]
and [Window | Prev] commands, the header area updates to reflect
the current window status. The F9 and F10 keys are short-cuts
for moving to the next or previous window, respectively.
A newly opened file name window displays the same directory as
the current window, and it also inherits the current window's
sort options, tagged files, and selection criteria. If you want
the new window to display a different directory or disk drive,
use the [Dir | Login New Directory] or [Dir | Login New Drive]
command to switch to the desired directory or drive.
Commands that operate on files only effect the directory shown in
the current window. For example, when you erase all tagged files
with the [Files | Erase File(s) | Tagged Files] command, only the
tagged files in the current window's directory are erased.
[Erase File(s)] does not effect any tagged files in other direc-
tories.
Closing a file name window removes the window from the screen
display. Closing a window has no effect on the files themselves,
it simply removes the window from the display.
Windows are very useful when working with two or more directories
at the same time. For example, when copying a set of files from
a hard disk to a floppy, or when moving files from one directory
to another.

OVERVIEW 2.20 DOCUMENTATION SUMMARY OF NEW FEATURES
APPENDIX A: SUMMARY OF NEW FEATURES
OverView version 2.20 adds several new features and enhancements
to the earlier version 2.10 release. Some of the significant
improvements include:
* The Enter key now performs a variety of additional functions:
- In the directory tree display, it "logs in" to the directory
under the dir pointer (like pressing 'L' for Login).
- In the main file name display, it views the file under the
file pointer (like Alt-V). If the file pointer is currently
over a directory name, you are logged in to that directory
(like F4).
- While viewing a file, it moves down a screen (like PgDn).
- It continues to select/invoke any highlighed menu entry.
* The Directory Tree display is now sorted by name.
* A "find file name" command has been implemented. The '=' key
starts a search for a matching file name in the current window.
Refer to the topic FIND FILE NAME in section 5 for more infor-
mation.
* File name scrolling has been changed considerably. In the
past, file names only scrolled up and down by rows. Now they
can also scroll left and right by columns. Left/right scrol-
ling will backup/advance one column of names at a time, while
up/down scrolling will backup/advance one name at a time. In a
related change, the file pointer will no longer wrap from first
to last or last to first file names, although the Home/End keys
still function.
* File names can now be displayed in either of the following
formats:
BIOSIO.ASM DIRECT.H | BIOSIO ASM DIRECT H
BIOSIO.OBJ DIRECT.OBJ | BIOSIO OBJ DIRECT OBJ
BMDOC.ARC DOSFILE.H | BMDOC ARC DOSFILE H
CHKMOUSE.ASM EMS.ASM | CHKMOUSE ASM EMS ASM
Use the [Other | Setup Parameters | Other Options | Display
Files as NAME EXT] option to select the style you prefer.
* An extra level of file information can now be displayed. There
is now a one column full info mode (as before), a two column
info mode (new), and a five column mode (as before). You can
cycle through the three modes using the Alt-I or [File | Extra
File Info] command (was [File | Full File Info]). You can
select whichever mode you prefer as a default with the [Other |
Setup Parameters | Startup Defaults | Extra File Info] options.
* You can now select default sort options with the [Other | Setup
Parameters | Startup Defaults | Sort Options] command.
32
OVERVIEW 2.20 DOCUMENTATION SUMMARY OF NEW FEATURES
* OverView now looks for its help (OV.HLP) and configuration
(OV.CFG) files in a directory pointed to by an environment
variable named OVFILES. Using this feature can shorten startup
speed and speed up access to help information, particularly
when the current directory is a floppy disk. If there is no
OVFILES env variable (or the directory it points to doesn't
contain the desired file), OverView will search the current
directory and then the PATH directories as before. Note:
OverView will continue to search for its directory tree file
(OV.DIR) in the root directory of the current disk, since there
can be a different OV.DIR file on each disk.
* OverView's initial directory can now be specified on the
command line. The command:
OV A:
will start OverView with the initial directory set to drive A:.
This change required the addition of the /M switch to specify a
file name mask on the command line. Before you could enter:
OV *.C
Now you must enter:
OV /M *.C
Refer to the topic COMMAND LINE PARAMETERS in section 5 for
more information on using directory names and the /M option on
the command line.
* Multiple DOS commands can be executed from the same command
line if the commands are separated by the '^' character. This
feature can be used wherever OverView allows entry of DOS
commands--User Defined Keys, Point-and-Go entries, [Xecute |
Dos Command], or [Xecute | Current File]. The commands will be
executed sequentially, from left to right.
* The Esc key will now exit OverView from the file name display,
without the "Quit (y/N):" or "Exit ... Return..." prompts.
OverView will exit to the current window's drive/directory.
The Alt-Q and Quit commands continue to operate as before.
* The Alt-K and Alt-M menu short-cuts have been exchanged to be a
better mnemonic aid. Alt-K is now for (K)opy-Tagged, and Alt-M
is now Move-Tagged.
A more complete list of the changes between OverView releases is
included in the READ.ME file that is distributed with OverView.
This list will be of particular interest to people upgrading from
an earlier release.
