About This Book
This book gives you short, clear answers to your questions about the HP 95LX
Palmtop PC. It does not replace the User’s Guide that came with the machine.
Rather, itis a companion book, “a pocket guide.” The User’s Guide documents each
command of the machine—helpful as a reference, but not so much for prioritizing
information. By contrast, this book distills out answers and anticipate your
difficulties, so that, for common topics, you need not search in the User’s Guide.
About Your Palmtop
What It Cannot Do
The HP Palmtop is a real PC—roughly equivalent to an IBM XT with a mono-
chrome display and MS-DOS version 3.22. And just like any such PC, itis limited
by the software available for it. Some programs for a desktop XT-compatible will
not work on the Palmtop—especially if they need a graphic display or extended
memory (see pages 111 and 123).
What It Can Do—If You Really Insist
The Palmtop is not really designed to write books, publish elaborate spreadsheets,
develop software, etc. You can do those things, but you’d be working harder than
necessary; far better to use a desktop PC for such tasks. For example, the Palmtop
has a Memo Editor with some standard word-processing features, but its keyboard
size is not the best for touch-typing a lengthy document. Likewise, the built-in 1-
2-3 program is great for analyzing, but you'll find it more convenient to prepare the
final presentation output of a spreadsheet on a desktop system.
6 0. First THOUGHTS

What It Was Designed to Do
The HP Palmtop isn’t meant to be used for everything that you use a desktop PC
for—just the things you need most often while “on the move:”
* A personal information manager: It offers you a complete address book,
appointment calendar and to-do list capabilities.
e An analytic tool: It gives you the “what-iffing” ability of Lotus 1-2-3 and the
ability to solve for missing variables (HP Solver).
¢ Enough memory capacity to store and manipulate quite a bit of data.
Ithas MS-DOS built-in, too, but that’s mainly so you can add other analytic tools—
and send/receive files to/from a desktop PC for the tasks it’s not so good at.
If You Already Know About PC’s
You'll find that many of the Palmtop’s features behave like those of other PC’s. All
the built-in applications have Lotus-like menus, from which you select any item
by typing the first character of its name. And, at the bottom of most screens is a
list of highlighted items corresponding to the function keys (F1){F©)) on the top of
the keyboard. To execute a listed command, press the corresponding function key.
One big difference between the Palmtop and other PC’s is that you can have
multiple applications open simultaneously in the Palmtop—and switch by press-
ing just one key (although you can’t access the DOS prompt or run a DOS-based
application unless all built-in applications are closed (more about this on p. 114).
If You Already Know About HP Calculators
If you've used any of HP’s recent financial calculators, you'll find that the Palmtop
Calculator feature can do just about everything they can (though it may take you
some time to adjust to how those calculator features look on the Palmtop’s screen).
The big difference between the calculators and the Palmtop is how the Palmtop
uses built-in Lotus 1-2-3 templates to do statistical and cash-flow analyses.
About Your Palmtop 7

Looking at the Keyboard
The HP 95LX keyboard is not the standard PC keyboard, but it’s probably more
convenient. Take a look:
Character Keys
¢ The alphabet keys are arranged in the standard q w e r t y format.
* The gold shift key (©) and the special character key (CHAR) give you access
to special punctuation, international, and symbolic characters (summa-
rized on pages 140-142). These keys are “sticky” keys: once you press (<),,
the next key you press will produce the shifted character. Unlike a
typewriter or standard keyboard, you don’t have to hold down (&) or
while you press other alphabet keys.
* The and (5) characters (bottom row) are given their own keys because of
their common use in Lotus functions and formulae.
Cursor Keys
* Above the numeric pad are the cursor keys: («,(»), (), (a), (HOME), END), DN),
and UP). Use the gold shift key (©) to get the gold-printed, “shifted”
versions of the four arrow keys. The tab ()) and back-tab (4) keys are also
cursor keys, but tab is actually a character that you can insert into text.
Calculator/Numeric Keys
* Thereisaverynormal-looking numeric pad to the right oftheqw erty keys.
* Thebottomrow oflettersontheqwertykeyboard (and theletter(L)) behave
differently when the calculator (&)) application is active. These functions
(),[x),XzY),R¥), (LAST), (STO),[Rc)and are printed in white—not gold like
the shifted functions—because they're active only in one application.
8 0. First THOUGHTS

Application Keys
* The keys marked in blue give you access to the eight built-in applications:
E3,023),3), (2), (@),), 3 and (SET LP) (OI).
Special Keys
e The key is in the upper-right hand corner.
e The and keys are special control keys that give you access to
various commands. These keys work only when pressed simultaneously
with another key, as in [CTRL[Z) or (ALT F1).
There are several keys that will “undo” something you've done:
en allows you to escape from your current menu choice, and will return
you to the previous menu or to the current application, whichever is
appropriate. Whenever you use nothing you’ve done within the
current menu will be saved.
— deletes the character currently underlined by the cursor.
— («) backspaces, deleting the character immediately to the left of the
cursor.
The (MENU) key displays the current menu of a built-in application (whichever
is open and current). Thus, acts like the key does in Lotus 1-2-3
(which is why a slash is printed under the (MENU) key).
Function Keys
In the middle of the top row are the 10 function keys (also called softkeys),
F1}-F0). The labels printed above these keys show their meanings in the
Lotus 1-2-3 application, butin all other applications, the current meaning(s)
of each function key will be listed on the bottom of the display immediately
above each key. For example: [ME or |SEERAS or [REMIZ. Of course, if the
space above a key is blank, it has no current meaning.

1. ORGANIZING INFORMATION
All About Files
The convenience of the HP 95LX is impressive. But, like any other Information
Manager, you must use it wisely and efficiently to gain its power and convenience.
To use it best, you must start by understanding its filing system.
Naming Files
The basic unit of organization on the Palmtop—as on any PC—is the file. Files
have different structures and formats depending on what kind of data they contain
and what programs use them. The HP 95LX uses the filename extension—the
three character suffix of a filename that follows the period (.)—to classify the
various kinds of files its built-in programs use. Here’s a list of these file extensions:
-ABK:
BAT:
«CHF:
«COM:
CTF:
DAT:
= DCF:
» ENV:
«EGN:
«EXE:
«ExM:
10
An Appointment Book data file that can be opened only from within
the Appointment Book application.
A DOS-based batch file—a kind of “macro for DOS.”
A file containing current settings or data for an added System
Manager application.
A DOS-based program or system command.
A Character Translation Facility file, used to translate characters
when communicating with a system with a different character set.
A file containing reference data used by the System Manager.
A Datacomm Configuration File, containing a particular collection of
settings needed for connecting to an external source via Datacomm.
A collection of the overall System Manager environment settings.
A file contains a list of Solver equations that can be opened only from
within the Calculator.
A DOS-based program which can be run only from DOS.
A System-Manager-based program which can be accessed (once it is
installed) only from within the System Manager.
1. ORGANIZING INFORMATION

FCF: A Filer Configuration File, containing a collection of Filer settings
needed for connecting—via the Filer—to an external source.
«HLP: A help file to be used from within a particular built-in application.
«LCF: ALogon Configuration File, containing a script used to automatically
log onto specific remote computers.
«PBK: APhoneBook data file that can be opened only from within the Phone
Book application.
«PCF: A Printer Configuration File that contains the Setup settings for a
particular printer.
«PCH: A graphics file compatible with the Business Card feature.
« TET: An ASCII Text file, editable with Memo Editor, that can be opened
by some built-in applications and many DOS-based applications.
«MWK1: A spreadsheet that can be opened only from within 1-2-3.
Saving Files
Each of the built-in applications allows you to save a file in two different formats—
the format particular to the specific application or in the ASCII Text format (i.e.
what the Appointment Book would look like if it were printed out). For example,
you could save a newly-created appointment book as an Appointment Book file
(with the «ABK extension) or as an ASCII Text file (witha « T&T extension). The
ASCII version would lack alarms and could only be edited within the Memo Editor.
To save a file in an application-specific format: From within the application (&),
(2), @), (BE) or (123)), press (MENU), (Flile, (Slave. You'll then be prompted to name your
file. You must use the proper extension so that you can retrieve the file again later
(this necessary extension is automatically offered by the prompt). Type in a name
(eight characters maximum) and press (ENTER).
To save a file as an ASCII file: From within the application, press (MENU), (PJrint,
(Flile. You'll then be prompted to name the file (the « TAT extension is automati-
cally offered by the prompt). Type in a name (eight characters maximum) and
press [ENTER].
All About Files 11

Using the Filer
The Filer is the “home base” of the System Manager operating system. Not only
does it help you organize your files into directories, it also lets you:
* Transfer files to/from a PC (via the Connectivity Pack—see pages 91-93);
¢ Run DOS-based programs on a plug-in RAM card (see page 120);
¢ Access the DOS Command line (see pages 114-115).
Disk Drives and the HP 95LX
File organization begins with the disk. On most desktop PCs, the drive designated
as A: is a floppy drive for removable diskettes; the C: drive is a fixed (or “hard”)
disk. To find its “boot up” information, the MS-DOS operating system checks the
A: disk first (if it exists), then the B: disk, then the C: disk.
Likewise, the HP 95LX comes with a plug-in drive into which you can insert RAM
or ROM cards. This drive is the A® drive. The internal combination RAM/ROM
card is the C3 drive. And, as usual, DOS looks at the A# drive (the plug-in port)
first upon boot-up—to see if it’s got a card plugged into it.
Pathnames and Directories
You denote each directory in DOS with abackslash (*). Each disk’s main directory
is called the root directory, whose name is only a backslash (nothing more). For
example, the root directory on the C= disk is denoted by C= ™..
The pathname of a file is a sequential list of the directories and subdirectories the
computer needs to follow (the “path”) to find the file. For example, the pathname
of a file called hiding .t xt, located in the worddocC directory of the
personal directory of project Sdirectory of the C: root directory would be:
c:sprojectshpersonal sworddocshiding.t xt
Notice how each subdirectory is separated by a *; the filename comes at the end.
12 1. ORGANIZING INFORMATION

The pathname is what makes a file unique. Two files can have the same name
(such as hiding .t xt) but not the same full pathname. In the Filer—and in
all applications—you may need to move “up” and “down” the paths in order to find
and store files where you want them: You move “down” a path by highlighting a
subdirectory and pressing ENTER). You move “up” a path by highlighting * « « and
pressing (ENTER). This ™ . a represents the parent directory—the directory contain-
ing the current directory. Practice in the Filer and get comfortable with paths,
pathnames and searching directories, before you attempt file transferring or file
translation with the Connectivity Pack.
The Built-In Files and Directories
On the Palmtop’s C# (internal) disk, the root directory (C2) is built-in and
contains, in turn, two built-in subdirectories and several other special files. To
displayit, press (F5) (E{=RE®) type C2 , and press (ENTER). You'll see a listinglike this:
Cis

—HOMEBUY WK1 4362 B3-28-91 r= 38a
STAT WK1 2444 83-20-91 r:38a
CHKDSK .EXE is the DOS CHecKDiSK command, which examines how a disk’s
memory is being used.
COMMAND . COM is the program that starts the DOS interface.
TF .COM is the DOS-version of a game called Tiger Fox (see page 121).
The underscore character (—) indicates built-in directories and data files. The last
five files listed above are 1-2-3 worksheet templates that you cannot delete or
modify (you copy them and modify the copies). And there are two subdirectories,
—DAT and _5YS also built into ROM. You can see the DAT subdirectory listed
here, but not the SYS subdirectory. Why not?...
All About Files 13

The SYS Subdirectory
—SYSis a hidden file—hidden, that is, from the directory listings of the Filer and
DOS. To get it to display, press [F5) (Ef=LER) type C*: “_5YS, and press ENTER).

Of course, the files listed above are for the U.S. release version (as the US on the
ends of the «HLP filenames indicate). You may copy files in —SYS to other
directories, but you cannot delete or change any of the files in this directory, nor
add files to it.
14 1. ORGANIZING INFORMATION

The dat Subdirectory
The dat subdirectory is visible from the Filer. In the Filer, press Fs) (HEAR),
c:~_dat, move to the —dat subdirectory. You will see a collection of
« ENVY files for each of the built-in applications, copies of some of the settings and
configuration files from the _SY& subdirectory (which may have been subse-
quently modified), and maybe a few other files that you've created. You can modify
the dat. directory to a degree: you can add and delete files and even change the
directory name (although you really don’t want to do that—each of the built-in
applications expects to find its current setup information in the dat. subdirectory).
Sorting and Organizing Files
The Filer’s primary use, of course, is to help you keep track of files. In your work
with your Palmtop, you will create a lot of documents—particularly with the
Editor and 1-2-3. You'll probably have a couple of phone books, at least one
appointment book, a collection of Solver equations, and a few DOS-based applica-
tions. You may also have some additional System Manager-compatible applica-
tions “attached” to keys on the keyboard.
Generally, you want to put any Phone Books and Appointment Books you create
into the —dat file (memory permitting, of course). This gives you quick access to
them. Then organize your other documents by creating subdirectories and then
moving files into the appropriate spots.
Creating a Subdirectory
1. Display the directory in which you want to place the new subdirectory, using
the arrow keys to select it and the key to display it.
2. Press (MENU), (D)irectory, (Clreate.
3. Press (») several times until you've moved to the end of the pathname.
4. Type the name of the subdirectory—making sure that you begin it with a
backslash (*)—and press [ENTER].
All About Files 15

Moving Files
To move files one at a time:
1. Highlight the file to be moved.
2. Press (EMS). You'll be prompted for the path to the new destination.
3. Type the new pathname (the filename is optional) and press ENTER). Be sure
to separate each directorylevel with (e.g. Ci “doc™corresphsept 91).
You can also move files as a group if all the files are in the same subdirectory. To
do this, you must “tag” each file in the group: Use the arrow keys to highlight it,
and press (IEF). To tag more than one file at a time, here are your options:
WES): Tags or untags the highlighted file.
Ar: Tags the highlighted file and all preceding files in the
current directory, as they're now sorted (see below).
(I=): Tags the highlighted file and all subsequent files in the
current directory, as they are now sorted (see below).
(HI 1) Tags all files in the current directory.
(AXE): Untags all files in the current directory.
Thus, to move a group of files:
1. Tag the group of files you want to move.
2. Press (iE). You'll be prompted for a path to the destination directory.
3. Type a path and press [ENTER]. If the destination directory doesn’t yet exist, at
the error message, press and create it (see page 15). Then move the files.
Sorting the Files in a Directory
You can rearrange the files in each directory in any one of four ways:
¢ Alphabetically, by filename: Press (MENU), (F)ile-Sort, (Flilename.
* Alphabetically, by file extension: Press (MENU), (Flile-Sort, (Extension.
* Chronologically, by last update: Press (MENU), (Flile-Sort, (Date/Time.
* Order of size (largest to smallest): Press (Flile-Sort, (S)ize.
16 1. ORGANIZING INFORMATION

Viewing Files
You can view a file directly from within Filer, although that’s not always very
helpful. Example: Highlight the COMPUSRY .DCF filein the _dat subdirectory
and press [ENTER]. You'll see this:

Not much useful information there! However, there are several types of files that
can be usefully viewed from Filer. Special files that you create in Memo Editor,
such as AUTOEXEC .BAT and CONFIG .SYS are text (ASCII) files. Any
« TRT files or «BAT files can also be viewed using Filer. Press (Fs) (Ef=1A®), type
ciyx_syshsysinit .bat to view the batch file which copies the
required files from the 54s folder (ROM) to the dat folder (RAM) where the
built-in applications expect to find them. You should see:

Editing Files
When you view files with the Filer, you may only look at them, you cannot edit them
in any way. If you want to edit a file, you must open the application that created
that file and then retrieve the file. .ABK files can be edited within the
Appointment Book, «PBK files within the Phone Book, « E@M within the Solver
section of the Calculator, «MWK files within 1-2-3, and any kind of text file ( «LST,
« TAT, «BAT, etc.) within the Memo Editor.

About Appointments
Every appointment consists of up to three pieces of information:
* A description of the appointment (Who with? For what?);
¢ The beginning time of the appointment;
¢ The duration of the appointment.
The HP 95LX allows you to add two other things to your appointments:
¢ Alarms to help you remember them;
¢ Special Notes to help you prepare quickly for them.
