SERIAL -- Serial Number Installer
I. INTRODUCTION
You write commercial software. You want to track which
copies of your program go to which purchaser. Or, you write
shareware software. Somebody registers a copy with you. Wouldn't
it be nice to know where that copy came from in the first place?
Well, solve both problems with SERIAL. This unique program
allows the easy insertion of serial numbers into any type of
file, whether text or executable. And, it remembers the last
number and how to patch your files as well.
II. SYSTEM REQUIREMENTS
* Dual floppy drives or hard drive plus floppy.
* CGA, Mono, or EGA card. If Mono card not in use,
SERIAL forces video mode 2 (Black/White 80 column).
* 32K of available memory for program.
* No color is used -- any monitor except 40 column
types are allowable.

III. STRATEGY OF OPERATION and TERMINOLOGY
The process of installing a serial number into a program
is actually quite simple. The program (or text file) is created
with a "dummy" serial number string. Then, SERIAL is told to
search the file for that string and replace it with another
string. A direct byte-for-byte substitution. You could do the
same thing with Norton Utilities (r) but it would drive you
crazy after about five files. SERIAL does the process in a
friendly, menu-driven operation, with error checks, automatic
number increment, and data logging. In order to understand the
remainder of this manual better, these terms will be used:
"TARGET FILE" -- This is the file which will be
patched.
"LOG FILE" -- The file which will contain location
information and last number used. There may be any
number of these if desired.
"SERIAL TEMPLATE" -- The string which will be placed
into the target file. This string has a designated
area for the serial number.
"SEARCH TEMPLATE" -- The dummy string in the target
which will be replaced.
"SERIAL NUMBER" -- a decimal number from 0000 - 9999
which is merged into the serial template.
"TILDE" -- the '~' character, which is used in the
serial template to indicate the position of the serial
number.
SERIAL Manual Page 3
IV. OPERATION
SERIAL requires no command line options. Simply execute
the program from any directory. Of course, DOS must be able to
locate SERIAL.COM, so make sure that it is in your current
directory or in a directory specified by your PATH environment
variable. The main menu will appear on the screen and a prompt
line will appear at the bottom:

+----------------------------------------------------------------------+
Briefly, the function keys are:
F1 File to Serialize
This key is used to specify the target filename. Be sure to
include any drive and path required. Maximum length is 32
characters total. A "beep" will sound for any illegal character,
or when the 32 character limit is reached. Press <escape> at any
time to abort the operation and return to the program prompt.
Press <enter> to complete the filename and return to the prompt.
The backspace key may be used to edit the filename before
pressing <enter>.
F2 Logging File
This key selects the file to use for logging information. It
operates the same as F1. After entering a filename, you will be
asked if you wish the filename to be installed as the default. A
response of 'Y' or 'y' will install the filename as a default,
providing SERIAL.COM is still available. Any other response
simply selects the file for current usage. To uninstall a
default file, press F2, then <enter>. Then, press 'Y' to the
question. A null filename causes any presently installed
filename to be uninstalled.
SERIAL Manual Page 4
F3 Serial # Template
This key is used to specify the serial template. Up to 16
characters may be specified. There must be at least one tilde
character. All printable characters are allowed. Backspace,
<enter>, and <escape> work as for F1 and F2.
F4 Search Template
This key allows selection of the search template. It functions
as for key F3, although the tilde characters are not required.
This string must be specified exactly as it appears in an
unmodified target file.
F5 Search for Location
After selection of a target file and search template, this key
is used to commence a search of the target file for the
specified search template. When found, location information is
saved within the program for use when installing the serial
number string.
F6 Modify the File
This operation places the final serial number string into the
target file. It requires prior entry of the target filename,
search template, serial template, and serial number. If a search
operation on the file has already been accomplished the
installation will be performed. Otherwise, an error message will
be displayed and it will be necessary to do a search (F5)
operation first.
F7 Auto-Increment
This key toggles the auto-increment function OFF and ON, with
the line always indicating the current state. If auto-increment
is ON, then the serial number will be incremented after each
modification operation. Otherwise, the number will not be
changed.
F8 Next Serial Number:
This line shows the current serial number. Use of this key
allows changing the number. As with other keys, backspace,
<enter>, and <escape> are active. However, this function allows
only numerical entry of four digits. If less than four digits
are entered an error message is issued. Use leading zeros if
needed.
F9 Update Log File
This key is active only if a logging file has been selected.
When used, the selected logging file is updated with current
data. The current serial number is always saved in the first
line of the logging file. The target filename is entered into
the logging file along with the selected search template and
location of the search template in the target. If the target
already exists in the logging file, its information is updated.
SERIAL Manual Page 5
This allows for updating a file's location information in the
event the target file is modified, changing the location of the
search template.
F10 HELP
This key opens up a second menu which allows selection of help
on each of the function keys. Pressing <escape> returns you to
the main menu.
ESC -- Return to DOS --
Use this key to quit SERIAL.
SERIAL Manual Page 6
V. TEMPLATE CONSIDERATIONS
A dummy serial number template must be placed in the
original target file. The template may be up to 16 characters in
length and contain any printable characters. This template will
be replaced in the target file by the serial number string,
which consists of the merging of the serial number and the
serial template. The serial template contains one or more tilde
characters, which indicate the location of the serial number.
For example, a portion of the menu may look thus:
F3 Serial # Template: A~~~~B
F4 Search Template: A0000B
F8 Next Serial Number: 1165
In this case, the target file will be searched for the string
A0000B when the F5 key is pressed. When the F6 key is pressed,
the serial number 1165 is merged into the serial template at the
tilde characters yielding a serial number string of A1165B. If
fewer than 4 tilde characters are present in the serial
template, only the appropriate number of digits from the serial
number will be merged, least significant justified. If more than
4 tilde characters are specified, the left-most four will be
merged and the remainder will be unchanged. If there are two
separate fields of tilde characters, such as "A~~~B~~~C" only
the leftmost will be recognized. Note that the length of the
serial template must be exactly the same length as the search
template, since it is not possible to patch a file with a
different number of bytes.
Consider the following C language line in the
traditional file "foobar.com":
puts("Serial Number: A0000");
To patch this file with serial number A1234 follow these steps:
Press F2 and type TEMP.LOG<enter>
Press F1 and type FOOBAR.COM<enter>
Press F4 and type A0000<enter>
Press F3 and type A~~~~<enter>
Press F8 and type 1234<enter>
Press F5
Press F7
Press F6
Press F9
This will install the number in the target file and update the
logging file. Upon completion the logging file "TEMP.LOG" would
look like this:
1235
foobar.com 0 0 0 0 0 A0000B
The several fields of zeros would actually be information
relating to the position of the search template in the file.
The serial number can be as simple as the above example,
or as complex as desired. Take the following example:
puts("Serial Number: MMDDYY-xxx-VVV");
The search string is MMDDYY-xxx-VVV. When creating a
distribution diskette of the program, the MMDDYY might become
the date the disk was created, the xxx would be the serial
SERIAL Manual Page 7
number (note the use of only 3 digits this time), and the VVV
might be the version number. Releasing serial number 702 on
9-23-86, version 2.37 would require a serial template entry of:
092386-~~~-237
and a serial number entry of
702.
In the above examples the tilde character has not been used in
the search template nor in the dummy program strings. There is
no reason that this couldn't be done, however. (In fact, I
program my own code in that manner.)
After SERIAL has the location of the search template,
either by searching or reading the location from the logging
file, installation of the serial number string is performed
without re-checking for the search template. This allows
changing the serial number string of a program which has already
been serialized, and which no longer has the dummy search
string. However, this also makes it very important to repeat the
search on the target file any time the target is modified in
such a way as to potentially change the location of the search
template.
SERIAL Manual Page 8
VI. THE LOG FILE
The log file is used to expedite operation of SERIAL.
Although several logging files may be used if desired, it is
probably more common to use a single file and cause it to be
installed as the default file.
When SERIAL is invoked with an installed logging file,
the file is immediately read and the serial number is retrieved
from the file. This eliminates the need to manually keep track
of the last number issued.
Whenever a target filename is selected, the logging file
is searched to see if that filename is already in the file. If
so, its search template is displayed on the F4 menu line, and
the location information is read from the file. It is then
unnecessary to perform a search operation. Of course, if the
generic target file has been modified the search template
location may have changed, so it will be necessary to do another
search to update the new location.
If a new target file is selected while a logging file is
in effect, the logging file will again be searched for
appropriate information. If the logging file is changed while a
target file is selected, the new log file will be read for its
serial number, and scanned for an entry pertaining to the
currently selected target file. Note that target filenames are
entered in the log file exactly as they are entered on the menu.
Therefore, "B:FOOBAR.COM" and "A:FOOBAR.COM" will have separate
entries, even though they may be the same file.
Be sure to do an update operation on the log file
whenever information has changed, such as a new target file, new
location search, or changed serial number. SERIAL will warn you
if you are about to do an operation which will lose information
which should go into the log file.

VII. ERROR MESSAGES
All error messages are displayed on the main menu in
place of the prompt line. Strike any key to clear the error.
"No logging file has been selected. <F2>"
An attempt was made to update the log file with F9,
except that there is no specified log file. Use F2 to
enter a log file name.
"No target file has been selected. <F1>"
An attempt was made to search or modify a target with
F5 or F6, except no target file has been selected with
F1.
"No template specified. <F3>"
An attempt was made to modify a file without first
selecting the serial template. Use F3 to select a
template.
"No search template specified. <F4>"
An attempt was made to search a target file without
first selecting the search template with F4.
"Template position not located. <F5>"
SERIAL has no knowledge of the location of the search
template in the target file. Either read in the data
from a logging file or perform a search operation with
F5.
"No serial number entered. <F8>"
A modify operation was attempted without first
specifying a starting serial number with F8.
"Failure opening logging file."
The specified log file could not be properly opened.
"Failure to open temporary logging file."
SERIAL uses a temporary logging file for updating the
specified logging file. This error occurs when the
temporary file SERIAL.TMP cannot be opened. If this
error occurs, the logging file will not be updated.
"Failure to open target file."
The specified target could not be opened for search or
modification.
"Read failure on target file."
During a search or modify operation on the target file
a fatal error occurred.
SERIAL Manual Page 10
"No serial number field in template. Redefine
template."
The serial template specified with F3 contains no
tilde characters for merging the serial number.
"Serial number must be 4 digits long."
The serial number selected with F8 had fewer than four
digits. Use leading zeros if necessary to pad number
to four digits.
"<F3> and <F4> templates not the same length."
The search and serial templates must be the same
length since it is not possible to alter the length of
the target file.
"Seek error on target file update."
During modification of the target file, a fatal error
occurred.
"WARNING! Error on writing target file. Target file
may be corrupted."
A write error occurred during the modification of the
target file. Integrity of the target file is in
question.
"Cannot locate SERIAL.COM to install defaults."
SERIAL.COM could not be located to install the default
logging file. This could be caused by switching disks
after SERIAL was invoked, invoking SERIAL with a
directory or drive path which is not in the PATH, or
by renaming SERIAL.COM to something else.
"Error on installation of defaults."
An error occurred during installation of the default
logging filename. Safety dictates replacing the
current SERIAL.COM with a backup copy.
"Altered logging information not save to disk."
This warning indicates that either the serial number
has been altered or new location information has been
collected, but an update of the logging file has not
been done to save the changes. After clearing this
error, the user is prompted to lose information or
not.

IX. SHAREWARE
By now, the shareware concept should be familiar to PC
users. In a nutshell, shareware is "try-before-you-buy"
software, reasonably priced and user-supported. This simply
means that you can get shareware software for free from anyone
who has a copy, or often from bulletin board systems. If you use
and like the program, then the author requests a donation to
support further software development. By registering and making
a donation, you will often also receive notice of available
upgrades or supplemental programs. Of course, payment under
shareware is voluntary, but if the program is useful and the
price is right, why not pay the dues and provide the incentive
and reward necessary to continue development of new and better
software?
SERIAL is shareware. If you like it and use it, please
register your copy on the registration form enclosed at the end
of this manual. You will be placed on a mailing list for future
upgrades, and receive the most recent distribution disk.
Online help is available through CompuServe, either by
using EasyPlex or a message in IBMSW or IBMHW forums. Sorry, but
online help is available ONLY to registered users.
Help is also available by mail. I will try to answer all
letters within 48 hours. Non-registered users must include a
SASE for a reply. The degree of help available to non-registered
users is purely discretionary.
SERIAL and all related documentation may not be sold
under any circumstances without prior approval of S.E. Margison.
Public Domain/Shareware distributors and Users Groups may charge
a nominal fee for copying and distributing this program and
Bulletin Board Systems may likewise carry it. Please contact me
for a complimentary copy to insure that you are offering the
most recent and complete release.
SERIAL and its documentation may not be transferred nor
exchanged in any modified form. If you really want to "hack" the
functions or the documentation, by all means do so; but don't
give the hacked version to anyone else. I cannot be expected to
help others use these functions if they are not the same as
distributed. Under no circumstances may the copyright notices be
altered or removed from the functions or documentation.
