CREDIT CARD SECURITY.DOC
Version 3.0
Almost everyone has at least one bank, department store, and gasoline
credit card. But what if you should lose your credit cards through
theft or damage. Do you know where to write to notify the credit
card company? Do you know where all of those papers that
came with your cards are? Probably not.
You can pay to have a private company notify all those credit card companies,
or you can have your PC keep track of your cards for you.
Credit Card Security is a simple menu operated, data handling program
that uses sequential files to store credit card information. And should
the need arise, the program prints out a form letter to each of the
credit card companies that you designate, notifying them of the loss,
and requesting a replacement card.
Each time the program is run you will be asked for the Drive and Path
for the program to search for your data file. This file will be made by
the program when you first enter your credit card information. The
program will name the file CREDCARD.DAT.
ENTERING DRIVE and PATH NAMES
If you are using a floppy disk to store your data, you would enter A: or B:;
depending on which drive you have your data disk in. If you have your data in a
directory on the floppy, other than the one that the credit card program is in
then enter the sub-directory name followed by a back slash. Example:
B:\CREDCARD\. If you are using a hard drive, and your data file is in the same
directory as the credit card program, then enter only the drive letter and a
semi-colon (Example: C:). If your data is in a different directory other then
the one that the program is in, then enter the drive and path name followed by a
back slash (Example: C:\CREDCARD\).
The program has six selections. The first selection displays the names, account
numbers, and expiration dates of the cards, and displays them on your screen or
prints them to your printer. Be sure that your printer is designated as LPT1.
You should make at least one hard copy for your records. If this is the first
time that you are using the program, then you should start with selection number
two; and enter your data. When displaying the file, the program will stop after
every 10 entries, so that none of the entries will scroll off of the screen.
press ENTER to display the next group of entries.
The second selection lets you add additional credit cards to your file
or create a new file. The program is set up to receive up to 50
entries. You'll be prompted for the name , account number, expiration
date, and the mailing address to write to in case your cards are lost
or damaged. When you have finished entering each entry, you'll be asked
to verify the information. Enter 'end' or 'END' at the credit card name
prompt to exit. The file will then be written to the drive and path that
you specified. If you are adding to an existing file, the data will be
appended to the existing file.
The third selection requires that you have a printer attached as LPT1
to your PC. The program will display the name of each credit card that
it has on file, and as each is displayed, you're asked if you want that
company notified. If your answer is no, the next card name is shown. If
your answer is yes, you'll be asked if the card was lost or destroyed.
The program will then print a form letter to that company, notifying
them of the lost or damage and requesting a new card. After the letter
is printed, the program will display the name of the next credit card
on file and the process will repeat until all the letters you want have
been printed.
The forth selection, allows you to delete a card that you have on file.
You will be asked to enter the name of the card exactly as it was
entered into the file. If you are not sure how you entered it, you
should either make a hard copy of all of your cards, or display them
first on your monitor. Use selection 1 for either of these. If the pro
gram finds a match in your file, it will display the card name, account
number, and expiration date on your monitor. You are then asked if this
is the card that you want to delete. If it is the enter 'Y' or 'y'. If
not, then enter 'N' or 'n'. If you answer yes the card will be deleted
and the program will overwrite your existing file with a new file of
the same name.
The fifth selection allows you to encode or decode your data file. Option one
will encode the file using a number between 1 and 254. You can not use the
number 13 because under certain conditions it encodes a carriage return as an
end of file marker, thus preventing you from decoding the entire file. Don't
worry because the program is setup to trap the number 13 if you enter it as a
code number, and prompts you to enter another number. Be sure that you write
the number that you use to encode the file down, and keep it in a safe place,
because you will need to re-enter this number in order to be able to decode the
file. The encode file will have the name CREDCARD.ENC, and after it is created,
you will be asked if you want to delete the uncoded (CREDCARD.DAT) file.
Option two will decode the CREDCARD.ENC file back to CREDCARD.DAT. When prompted
to do so enter the number that you used to encode the file. After the file is
decoded you are asked if you want to delete the encode (CREDCARD.ENC) file.
Remember that if you have encoded the file, you must encode the file before you
can use the rest of the program.
The third option will return you to the main menu of the program.
The sixth selection will allow you to exit the program.
