ZipZap 7.13 Jan. 1991 Introduction
[*] Welcome!
Thank you for trying ZipZap 7.13, a program designed to allow
computer users to get to the "meat" of disk files and sectors.
[*] Shareware / How You Can Make Money
ZipZap 7.13 is distributed as shareware, and folks who use the
program should register with KeyStrokes Computer Works. We feel
ZipZap is a great value - the registration fee is only $15.00
(plus sales tax for Kansas residents - see the file ORDER.DOC for
details).
Registration does much more than give you a clear conscience -
you might also earn commissions. When you register with us,
we'll send you the latest version of ZipZap, embedded with a
personalized serial number. For each subsequent registration we
receive bearing your serial number, we will send you $5.00. If
you pass ZipZap along to your friends, coworkers, etc., and just
three of them register, your copy is essentially free. Shareware
works only when users support authors, and we hope this incentive
will encourage you to register your copy today!
[*] INTRODUCTION
ZipZap 7.13 allows you to view and/or modify a file or disk sector
by sector. The data from the file or disk sector is displayed in
two different formats: hexadecimal numbers and ASCII text. The
information may be changed in either format. ZipZap allows to you
to see data (which may be the contents of a text file, program
file, or any other type of DOS file, as well as a floppy or hard
disk) exactly as it is stored on the disk, and allows you to make
modifications to that data.
IMPORTANT NOTE: If you plan on making changes to a file, do
yourself a favor and make a backup copy of the file first, and
make the changes to the backup file. If all goes well, you've
only added one or two simple steps to the process, and if you
seriously trash a big important file, you'll be glad you didn't
do it to the original! As for zapping a disk, DON'T DO IT UNLESS
YOU KNOW WHAT YOU'RE DOING. Note that neither KeyStrokes
Computer Works nor the author are responsible for anything you do
with ZipZap. If you blitz your original PageMaker disk, your
outrage will have to be self-directed.
[*] PROGRAM REQUIREMENTS
ZipZap 7.13 requires DOS version 2.0 or later and should work on
any IBM compatible computer with at least 128K of RAM.
-3-
ZipZap 7.13 Jan. 1991 Introduction
ZipZap will zap files on any logical drive present in the system,
but will only accept drive designators from A: thru H: for disk
zapping. ZipZap is not designed to handle logical files or disks
over 30 megabytes (64K sectors) in size.
[*] Getting Colorful
ZipZap contains a built-in customization routine that can be
invoked while using the program or from the DOS command line.
Using this routine you can modify ZipZap's colors to your liking,
specify whether ZipZap should display numbers in decimal or
hexadecimal format, and indicate whether or not you want ZipZap
to double check with you before over-writing a sector or exiting
to DOS.
To run the customization routine from the DOS command line simply
include the parameter "/I" in the command line:
ZIPZAP70 /I
This alerts ZipZap to the fact that all you really want to do now
is set up the colors. A couple of things will happen here.
If your system is running under DOS version 3.0 or later, ZipZap
will go directly to the customization screen. If, on the other
hand your working with an earlier DOS version, you will be
prompted for a file name....
-----------------------------------------------------------------
| Enter the filename you have chosen for ZipZap 7.13: ZIPZAP70.EXE |
-----------------------------------------------------------------
If you have chosen to rename ZIPZAP70.EXE to something a bit
shorter, enter that name here. THE .EXE EXTENSION MUST BE
INCLUDED!
Once you press Enter ZipZap will look for the filename you
entered and will alert you if that file cannot be found. If
everything went well, you will move on to the customization
screen, which looks like this:

=======[ Esc:Done F3:Monochrome F4:Color F5:Read current settings ]========
The list in the upper left part of the screen shows the different
options and their current values. At the upper right is a mini-
representation of the ZipZap work screen. The line at the very
bottom of the screen reminds you of a few important keys.
The first four options in the list are program "toggles". A
toggle is something that is turned either on ("Yes") or off
("No"). When the arrow pointer is directed at one of these
toggles, you may change it by pressing <Y> for Yes, <N> for No,
or <Enter> to switch between the two.
"Confirm Disk/File Writes" indicates whether ZipZap should ask
the user for confirmation before writing sector changes to disk.
WE HIGHLY RECOMMEND YOU LEAVE THIS SET TO YES!
"Exit Without Confirmation" allows you to have ZipZap quit
immediately when one of the exit keys is pressed (Esc, F9, Ctrl-
C, or Ctrl-Break).
"Display Values in Hex" is the same as the Shift-F7 toggle, but
indicates which state to be in by default. When set to yes, all
sector number and offset values will be displayed in hexadecimal,
and all numeric input is expected to be in hexadecimal notation.
-5-
ZipZap 7.13 Jan. 1991 Getting Colorful
"International Characters" is for those who use ZipZap on
foreign-language program files and the like. When this is set to
"Yes," ZipZap will display the international character set when
the ASCII toggle is set to alphabetic characters only. When set
to "No" ZipZap will display only the U.S. ASCII set. This toggle
is the same as the Alt-F7 toggle key.
Now, if all these toggle options are horribly confusing to you,
just leave them set to their default values.
Move through the list of options with the up and down arrow keys.
To change the color of an item use the arrow keys to point the
arrow at the item, then press <Enter>. The "Pick a Color" window
with all the possible colors is displayed and using the arrow
keys you may select the new color. Press <Enter> when the
desired color is selected, or press <Esc> to leave the color as
is. Each time a change is made, the mini ZipZap screen will be
updated to reflect the changes, so you can see immediately if the
color or attribute you've chosen is really to your liking. The
display looks like this when the "Pick a Color" window is active:

ZipZap has built-in defaults for both color and one-color systems
that can be called up at any time by pressing the F3 (monochrome)
or F4 (color) key. If you make a bunch of weird changes and
decide you don't like them, pressing one of these keys will give

you a place to start over from!
When you've got the color combination you like, or when you're
done, press <Esc>. You'll then see:

Pressing "S" at this point will update the ZipZap program file to
reflect any changes you've made. You may press "Q" to quit the
installation without actually writing the changes, or hit <Esc>
to return to the customization screen. Note that this whole
process may also be done from within ZipZap while zapping a file
or disk! See below under the Read Mode for details.
[*] GETTING STARTED (Okay, what do I do now?)
ZipZap may be invoked either with or without a filename or disk
letter in the command line.
A>ZIPZAP70 -or- A>ZIPZAP70 target
"Target" in the second example is either a filename (like
LETTER.DOC) or a drive designator (like A:, B:, C:, etc.)
-7-
ZipZap 7.13 Jan. 1991 Getting Started
Specify /B in the command line to suppress the color display.
This is especially useful to folks who setup ZipZap to run on a
color monitor but find themselves occasionally needing to use it
with a color/graphics card hooked up to a composite color or
monochrome monitor. See the section on the Del key under READ
MODE for more information.
A>ZIPZAP70 /B -or- A>ZIPZAP70 target /B
The entire filename and extension of "target" must be given, or
ZipZap will tell you that the file can't be found. When started
up this way, the filename screen is bypassed after the opener,
and you are brought directly to the main ZipZap work screen. If
the filename specified in the command line is NOT present in the
specified directory or on the specified disk, a "File Not Found"
message and a cute little beep will alert you to the fact that
you goofed, and you'll be dumped back at the DOS prompt. Not
very polite, but heck, at least the program won't melt your disks
or anything nasty like that!
NOTE: As mentioned in the installation section, you may by all
means rename ZIPZAP70.EXE to make its use more convenient.
On my disk, I call it ZAP, since it's easier to type in
"ZAP filename" than "ZIPZAP70 filename." I keep ZAP.EXE
in the DOS path so that it may be invoked from anywhere on
the disk. You must, of course, retain the .EXE extension
if you rename ZIPZAP70.
When you invoke ZipZap without a filename or disk letter in the
command line, you will see the following:

ZipZap 7.13 Jan. 1991 Getting Started
As the dialogue box at the bottom of the screen indicates, there
are some editing keys available when entering the path and
filename, as well as ANY time you get the little dots in the
input field. These special keys are:
Arrows: The right and left arrows move one character right and
left, respectively.
Ins: Inserts a space, and pushes the existing text to the
right one space.
Del: Deletes the character under the cursor, and "sucks" any
text to the right in to fill the gap.
Bksp: The backspace key (labelled "<---" on a lot of
keyboards) deletes the character to the left of the
cursor, and pulls text from the cursor right one space
to the left.
Home: Moves the cursor to the beginning of the line.
End: Moves the cursor to the last character in the line.
Ctrl-E: Erases the contents of the line completely. This is
useful when using the Seek or Search functions a lot,
since ZipZap "remembers" your input each time, and
makes that the default answer, which you may not want.
Sure beats hitting Delete 26 times!
Esc: Exits the current function without taking any action.
Hitting Esc is always a safe move when you're not sure
what to do.
Enter: Indicates you're done with the line, and passes the
input to the routine you're working with.
At this time, enter the name of the file or disk you wish to
work with. Full pathnames are supported (C:\WS\DOCS\MYFILE.TXT,
etc.), and the entire pathname must be given unless ZipZap is
invoked from within the directory containing the file you want
to zap. To zap a disk, enter the proper drive letter followed
by a colon (e.g. A:, B:, etc.) Note that you have the option of
simply pressing Esc or hitting Enter without a file or disk name
to exit the program.
-9-
ZipZap 7.13 Jan. 1991 Getting Started
If ZipZap can't find the file specified, you'll see:
---------------------------------------------------------------------
| |
| Enter file/disk (Esc:exit CR:dir):MYFILE.TXT........................|
| ----------------------------- |
---------| |-----------------------------
| File not found: try again! |
| |
-----------------------------
A short alarm will sound alerting you to the error, and then you
are prompted to try again. You may remove the "File not found"
message quickly by pressing any key, or wait until the message
disappears on it's own (only 3 seconds or so.)
If you specified an invalid drive letter, you'll see:
---------------------------------------------------------------------
| |
| Enter file/disk (Esc:exit CR:dir):F:................................|
| ----------------------------------- |
---------| |-----------------------
| Invalid drive letter: try again! |
| |
-----------------------------------
The alarm will sound, and you are prompted to try again. You
may also remove the "Invalid drive letter" message quickly by
pressing any key.
If you pressed the Enter key without specifying any particular
drive or file, you will see this:
[ Directory ]--------------------------------------------------------
| |
| Directory path? C:\TURBO\.......................... |
| |
| |
---------------------------------------------------------------------
The current (default) directory name will be displayed. If you
want the directory of a different drive or path, press Ctrl-E to
erase the default directory, and enter the path you want. If the
directory or drive you enter is invalid, the Directory window
will simply disappear, and you can try all over again!
NOTE: When specifying a subdirectory, make sure you include the
"\" on the end, as in the example above.
-10-
ZipZap 7.13 Jan. 1991 Getting Started
Next ZipZap will read the directory you asked for (you'll see a
brief message that says "Reading Directory...") and pop up
another window containing all the files in that directory. The
window looks like this:
[ C:\ZIPZAP ]==========
| .. DIR |
| bootsect.pas |
========================================| cdisp .pas |======
| | coltable.pas | |
| Enter file/disk (Esc:exit CR:dir): | create .bat | |
| | dosver .pas | |
========================================| extkeys .pas |======
| getkey .pas |
| hexfunc .pas |
| hexfunc .tpu |

| hexstrng.pas |
| hexstrng.tpu |
| makedisk.bat |
| makereg .exe |
| makereg .pas |
| mapfiles.exe |
| mapfiles.pas |
=======================
The first file name will be highlighted. You can move the
highlight up and down using the arrow, Home, End, PgUp, and PgDn
keys. You may switch disk drives by pressing Ctrl-X where X is
the drive letter in question. For example, Ctrl-D switches the
directory display to drive D:. When the file you want is
highlighted, press Enter, and ZipZap will go on to the Main Work
Screen.
If you decide this wasn't such a good idea after all, press Esc
to back out of the directory window. Simple!
[*] THE MAIN WORK SCREEN (What's all this garbage?!)
Once ZipZap has verified that the file you asked for is indeed on
the disk, or that the disk drive letter is valid, you are brought
to the main work screen. It looks like this:

The top line, called the STATUS BAR, keeps track of where you
are, and what you're doing (sounds kinda like a wife, doesn't
it?! Sorry, ladies!) Four basic pieces of information are
displayed here:
1. The first is the name of the file or disk you're currently
zapping. In the case of files, if the entire pathname\
filename will fit here, it is all displayed; otherwise only
the file name is displayed.
2. The current sector number being viewed or zapped. ZipZap
7.0's capacity is a little over 65500 sectors - the
approximate size of a 30 megabyte hard disk.
NOTE: PC-DOS and MS-DOS versions prior to 4.0 limit disk
size to 30 megabytes. ZipZap is not intended to work with
-12-
ZipZap 7.13 Jan. 1991 The Main Work Screen
certain "extenders" on the market which allow DOS to handle
hard disks larger than 30 megabytes as one drive. ZipZap
has not been tested under DOS 4.0. If you're a 4.0 user,
please let us know what success or problems you have.
3. The total number of sectors in the file. Useful when you
know you need to find something "about half way" through the
file. Also, a "scroll bar" of sorts is continually updated
on the left edge of the screen indicating relative file/disk
position.
4. The mode currently in use. While reading sectors, this is
set to Read. While in zap mode, this reads Edit. If the
current sector is the first in the file, (TOF) is displayed
(for Top Of File) and if the current sector is the last in
the file, (EOF) is displayed (for End Of File.)
The majority of the screen is devoted to the WORK AREA. The
work area contains 2 components:
1. Hex contents of the current sector. This area displays the
contents of the current sector in hexadecimal format. Each
line (except for the last) contains the hex values of 24
bytes. The last line contains 8 bytes. Every other byte is
shaded yellow on color screens, light gray on monochrome and
composite screens, so you can distinguish between bytes more
easily.
2. ASCII contents of the current sector. This is the same data
presented in section 1, but in ASCII format. This is
especially useful when trying to locate text strings in a
file for modification. Unless you think in hexadecimal,
you'll probably find it easier to locate things here. The
color or attribute of the bytes on this side correspond to
the same byte on the hex side for easy reference.
[*] MODES (What the heck am I doing?)
There are really two modes of operation in ZipZap: the Read and
Edit modes. We'll discuss these at length individually. Simply
stated, while in Read mode you can't do much besides look around
the file and read what's there. In the Edit mode, you can't do
anything but edit the current sector. Now, let's take a long
look at these two modi operandi....
-13-
ZipZap 7.13 Jan. 1991 Read Mode
[*] THE READ MODE (Let's see what we got here.)
At the bottom of the screen is a line listing several function
keys and a very brief hint as to their function. A more
complete list can be viewed by pressing the Help (F10) key:
[ Read Mode Command Keys ]---------------------------------------
| |
| PgUp: Read the PREVIOUS sector Home: Go to the FIRST sector |
| PgDn: Read the NEXT sector End: Go to the LAST sector |
| |
| F1: Open/Close Recovery File Ins: Color ON |
| F2: Write Sector to Recovery Del: Color OFF |
| F3: Enter the EDIT mode F4: SEEK a sector |
| F5: Select another FILE or DISK F6: Find HEX sequence |
| F7: Toggle non-ASCII on/off F8: Search for TEXT |
| Shift-F2: Save a RANGE of sectors to the Recovery File |
| Shift-F4: Go to sector containing absolute offset |
| Shift-F7: Toggle numeric values between Hex & ASCII |
| Alt-F7: Toggle Display of International Character Set |
| Shift-F8: Repeat last search from the current sector |
| Ctrl-P: Print individual sector or entire file/disk |
| Ctrl-R: Record length for highlight / turn highlight off |
| Ctrl-Z: Configure colors, confirmation on/off for ZipZap |
| F9 or Esc: QUIT ZipZap |
| F10: Help (this window) |
| |
----------------[*] Press any key to exit Help [*]---------------
Here's an overview of these functions:
PgUp/ These are the workhorse keys. Use these to move
PgDn through the file a sector at a time. PgDn reads
the next sector to the screen, and PgDn reads the
previous one. The arrow keys and tab key serve similar
functions. Gentle little beeps will alert you if you
try to PgUp from the top of the file (TOF) or PgDn from
the end of the file (EOF).
Home Displays the first sector in the file or on the disk,
always numbered 0. (TOF) is displayed next to the mode
in the status bar. Home does nothing if you're already
at the top of the file.
End Displays the last sector in a file or the last logical
sector of a disk. (EOF) will be displayed next to the
mode in the status bar. The End key is inactive when
you're already at the end of the file.
-14-
ZipZap 7.13 Jan. 1991 Read Mode
F1 Open/Close Recovery (Save) File. This is almost always
used when zapping a disk. You can use the Save File to
store "lost" data, i.e. data from a file that has been
long deleted and is no longer recoverable with a
program like Norton Utilities or PC-Tools. You can
also use this function to save particular disk areas
like the boot sector, directory, FAT sectors, etc., in
order to examine them with your favorite file-based
utility, disassembler, etc.
When you first press F1 you'll get a dialogue box like
this:
[ Open a Recovery File ]===============================================
| |
| File to use for saving (Esc to close): ............................ |
| |
=======================================================================
Enter a filename to which "recovered" data will be
written. Any legal DOS filename will do. If the file
already exists, you'll be asked whether to add saved
sectors to the end of the file (Append) or write over
the beginning of the file (Overwrite) by this dialogue
box:
=================================================
| |
| File found: <A>ppend or <O>verwrite? (A/O): |
| |
=================================================
Just press "A" or "O" to indicate your choice.
* Whenever a Save File is open, you'll see "[S]" in the
upper right part of the screen on the status bar.
Pressing F1 a second time, or any time a Save File os
open will produce a dialogue box inquiring whether you
wish to close the Save File:
[ Yes or No ]---------------------------
| Do you want to close SAMPLE? (Y/N): |
----------------------------------------
Press "Y" or "N" to indicate your choice. If you
inadvertently close a Save File, you can press F1 again
and specify the same filename, and tell ZipZap you want
to <A>ppend data to the file. That way nothing gets
lost!
-15-
ZipZap 7.13 Jan. 1991 Read Mode
F2 Write Sector to Recovery. Pressing F2 will save the
current sector's data to the Save File specified with
F1. If no Save File is open, you are brought to the
Open Recovery File box (described above.) After the
data has been saved, a dialogue box will pop up briefly
telling you which sector in the Save File was just
written:
===========================================================
| |
| Sector #14 written to SAMPLE |
| |
===========================================================
This box will disappear very quickly, but you can press
a key to dispose of it immediately if you wish.
Shift-F2 Save a Range of Sectors to the Recovery File. There
are ties when several contiguous sectors need to be
saved, and stepping through them and saving them one-
by-one with F2 is a bit tedious. Shift-F2 has been
added to allow an entire range of sectors to be
specified for writing to the recovery file. If no
recovery file is open when Shift-F2 is pressed, you
will be prompted to enter a filename for one.
Remember when entering the beginning and ending sectors
to write that if you have set ZipZap to operate using
Hexadecimal numeric displays, either via the
Customization routine (Ctrl-Z) or by pressing Shift-F7,
the sector numbers you enter will be interpreted as
being in hex.
F3 Enter the Edit (zap) mode. This is how you get to
actually zap the current sector. The mode changes to
"Edit" to let you know that you're ready to zap away to
your heart's content! More on this later.
-16-
ZipZap 7.13 Jan. 1991 Read Mode
F4 Seek (go to) a particular sector. Pressing F4 will
bring up a prompt asking for the sector number to read.
Use this when you know the sector(s) you need is not
near the beginning of the file. If you specify a
sector number higher than the number of sectors in the
file or on the disk, the last sector will be read into
memory. The dialogue box for this function looks like
this:
[ SEEK a sector ]----------------------
| |
| Sector number to seek: ...... |
| |
---------------------------------------
Shift-F4 Seek to the sector containing absolute byte offset.
WHAT?? Well, sometimes a person needs to change one
particular byte (after doing a DOS COMP operation, for
example.) This function will ask for the byte offset
to seek (in decimal) and will go directly to the sector
containing that byte, highlighting it with the same
color that's used for hex and text searches (see F6 and
F8 below.) The dialogue box for this function looks
like this:
[ SEEK Offset ]------------------------
| |
| Byte offset to seek: ........ |
| |
---------------------------------------
F5 New file. This will take you back to the file
selection screen, where you may choose a new file to
zap.
-17-
ZipZap 7.13 Jan. 1991 Read Mode
F6 Search for Hex Sequence. F6 and its complimentary key,
F8, are both very handy to have around! See the
description of F8 below for details on finding a text
string. When you want to find a particular sequence of
hexadecimal values, hit F6. ZipZap will ask for the
text to search for, and the sector number to start
searching from. If an illegal sector number is given,
the search will start at sector number zero. If no
search text is specified, or if Esc is pressed, the
search is aborted. The Search dialogue box looks like
this:
[ Find Hex Sequence ]--------------------------------------
| |
| Enter the sequence of hexadecimal values you wish to |
| find. Each must be 2 characters long (0A 1F 3B, etc.): |
| |
| 1A 2B 32 32 01.......................................... |
| |
| Start at sector: 22... |
| |
-----------------------------------------------------------
If the hex sequence asked for is found, the search will
stop, a message will be displayed, and the sector
containing the search values will be displayed. The
values searched for will bw highlighted (green in
color, bright white in monochrome.)
If the sequence of bytes is not found, a message to
that effect will be displayed, and the sector that was
on screen before the search started will be displayed.
Once a search is underway, you may stop it by pressing
any key. When you do this, a message will indicate
that the search has been aborted, and the sector that
was on screen before the search started will be
displayed.
F7 Toggle non-ASCII display. I know, you're saying, "Hey,
there ain't no F7 at the bottom of the screen!" Well,
we couldn't fit EVERYTHING on that one little line. In
fact, this key is included on the Help screen (F10).
Pressing F7 the first time will force ZipZap to display
characters outside of the standard ASCII set (graphics,
etc.) Pressing the key again will turn this feature
off. Toggling this on will allow you to see on the
ASCII side of the display characters used to make up
borders, as well as a lot of garbage! The ASCII
display is easier to read without these characters,
-18-
ZipZap 7.13 Jan. 1991 Read Mode
since only the "readable" ones show up (all others are
displayed as ".")
Shift-F7 Toggle numeric display. Some folks prefer to work in
hex, some prefer decimal. Pressing Shift-F7 switches
between these two bases. When in hex mode, most
numeric displays (the sector number, for instance) will
have leading zeros, while in decimal mode they do not.
Alt-F7 Toggle International Character Display. Those who work
outside of the U.S.A. might find this toggle handy.
When set on, international characters are displayed
along with the USASCII set. This toggle can be set on
by default through the customization screen.
F8 Search for text. When you want to find a particular
occurrence of text, hit F8. ZipZap will ask for the
text to search for, and the sector number to start
searching from. The same rules apply to F8 that do to
F6. The Search dialogue box looks like this:
[ Find Text String ]---------------------------------------
| |
| Enter text to find: This is a test |
| |
| Start at sector: 1.... |
| |
-----------------------------------------------------------
You'll get the same messages with F8 that you get with
the F6 search. See above for the details.
Shift-F8 Pressing this key combination repeats the last search
operation (hex or text.) A box pops up telling you
that ZipZap is looking for the next occurrence of the
hex sequence or text string. Everything else works
just like it does with the F6 and F8 keys.
-19-
ZipZap 7.13 Jan. 1991 Read Mode
F9 Quit. Exit to DOS. Go away. Leave. Etc. A little
dialogue box pops up asking you to confirm your desire to
quit. Simply press "Y" to exit. Striking any other
key returns you to the read mode. The dialogue box to
confirm your wish to exit looks like this:
[ Interruption! ]----------------------
| |
| F9 has been struck. |
| |
| Exit to DOS? |
| |
---------------------------------------
Striking Esc, Ctrl-C, or Ctrl-Break will produce the
same results as hitting F9.
F10 Brings up the help screen. Press any key to return to
the program.
Del Turn color off. ZipZap automatically detects the type
of display adapter in use (monochrome or color/
graphics.) For users who have a composite one-color
monitor hooked up to a color/graphics card, the display
may be unreadable. Pressing Del will clean up this
problem by changing the display to black and white;
this overrides any color settings made in the
customization routine.
Ins Returns the display to the regular, colorful mode. The
colors will be those specified in the customization
routine.
Ctrl-R Our local Sysop, Benn Gibson, gets the credit for
annoying me to the point of finally including this
function ("This ones for you," Benn.) Ctrl-R toggles
the RECORD HIGHLIGHT function on/off. This feature
will come in handy mainly for programmers, consultants,
and hackers (Benn is all three.) It uses varying
attributes on-screen to highlight fixed-length records.
When Ctrl-R is first pressed, you will see:
[ Highlight Records ]==================
| |
| Enter Record Length: .... |
| |
=======================================
Enter the record length you desire, then press Enter.
ZipZap will then vary the attributes so that individual
-20-
ZipZap 7.13 Jan. 1991 Read Mode
records can be easily identified. This highlighting
will stay in effect in the Edit mode!
Simply press Ctrl-R again to turn this feature off.
Note that this function does not isolate records for
viewing and editing - you still see an entire sector's
worth of information, and more often than not records
will cross sector boundaries. The highlight colors are
kept consistent for each record, i.e. if a record
starts off in one sector in white on blue, it will
continue in the next sector with that same color.
Ctrl-P Long ago and far away ZipZap had some rudimentary
printing routines that were dropped along the way.
Well, the requests have been pouring in, so the
printing functions are back and have been enhanced.
Pressing Ctrl-P while in the Read Mode brings up a
dialogue box asking whether you want to print only the
current sector or the entire file or disk. While
ZipZap is printing your sector(s) a window displays its
progress. Press ESC to abandon printing at any point.
Ctrl-Z You may invoke the color customization routine by
pressing Ctrl-Z. It will work just like it does when
the "/I" command line option is used, but will return
you to the file or disk being zapped rather than
exiting the program.
[*] ZAP!!! THE EDIT MODE (Let's play!)
As mentioned earlier, the edit (zap) mode is entered by pressing
the F3 key. A couple of things change when you do this. The
line at the bottom of the screen is altered to reflect a new set
of command keys, the mode changes to Edit, and a full-block
cursor appears over the first character in the hex part of the
work area. One of the first things you'll notice is that the 1st
byte of the sector (the one the cursor is on) changes color on
BOTH sides of the display. This will assist you in keeping track
of exactly which byte the cursor is on. The cursor changes to
flashing bright white on both color and monochrome screens, so
it's easy to keep track of. Now it's time to have fun!
As in Read mode, F10 brings up a short help window. It looks
like this:
-21-
ZipZap 7.13 Jan. 1991 Edit (Zap) Mode
[ Edit Mode Help ]-------------------------------
| |
| Home: Go to first byte End: Go to last byte |
| |

| to Read mode. to disk. |
| |
| * TAB selects Hex or * In ASCII mode, type |
| or ASCII mode. new text. |
| |
| --- Press any key to exit Help --- |
-------------------------------------------------
Here's an overview of these functions:
Tab Pressing the Tab key switches the cursor to the other
side of the display. The first time it's pressed, you
are put in the ASCII side. Press it again, and, ta da!
You're back on the hex side. Note that when Tab is
pressed, the cursor's RELATIVE position in the sector is
maintained.
Arrows The arrow keys move you around the screen - up, down,
right, left, just as you'd expect. If you move past a
left or right border, the cursor "wraps" around to the
other side of the display. The arrow keys work the same
in hex and ASCII zap displays.
NOTE: At the bottom of the hex side of the work area
you'll notice a small area telling you which byte the
cursor is currently on ("Currently on byte: 0"). This
is updated after each keypress, so you'll always know
exactly where in the sector the cursor is located. The
range, of course, is 0 - 511.
Home Pressing Home moves the cursor to the first byte in the
sector.
End End moves the cursor to the last byte in the sector.
0-9/A-F Pressing these keys will alter the byte under the
cursor. The cursor will move to the right with each key
pressed.
Any While on the ASCII side, you may change the contents of
the sector by simply typing in new text.
-22-
ZipZap 7.13 Jan. 1991 Edit (Zap) Mode
Notice that as each key to change a byte is pressed, the
new letter or number is changed to a different color
(whatever has been set in the customization routine).
These bytes will remain their new color until you write
the changes to disk or abort the Edit mode altogether.
Note that on the ASCII side of the display, new spaces
may be detected as the cursor itself changes to the
"edited" color when it is over a new space. This means
you can always tell when ANY byte has been changed from
its original value!
Esc/F3 Pressing Esc or F3 a second time will take you
immediately back to Read mode WITHOUT SAVING YOUR
CHANGES. This is nice when you've really botched up a
sector or are just practicing! In effect, F3 then will
toggle between the Read and Edit modes, but does NOT
save changes when leaving Edit mode. See the
description of the F4 key for more.
F4 Write sector to disk. Your MUST hit F4 to record any
changes you've made to the sector. Unless you've
customized ZipZap to operate in the "dangerous" mode,
you are prompted for confirmation of this could-be-
disastrous-if-you-don't-know-what-you're-doing task.
The dialogue box to confirm your wishes looks like this:
[ WRITE the Sector ]-------------------
| |
| ARE YOU SURE you want to |
| |
| make these changes to sector |
| |
| number 0? |
| |
| <Y>es or <N>o: |
| |
---------------------------------------
Pressing "Y" indicates you do in fact want to make these
changes permanent. Pressing "N" (or any other key
besides "Y", for that matter) returns you to the Edit
mode right where you left it.
The actual disk update (assuming you pressed "Y") is
very fast, and if you have many buffers set in your
CONFIG.SYS file, it'll seem like nothing happened at
all. Fear not, the changes have indeed been made! You
will be transported back to the Read mode immediately
after the disk has been updated, so you can choose
another sector to zap, or exit, or get a drink, or
