          What Is DosBank?

          DosBank is a Credit Card validation program developed 
          for individuals and companies that take credit card 
          orders over the telephone without any immediate means
          of verification.
            
          The program has saved our company thousands of dollars,
          and will do the same for yours.  This version of the
          program is laid out in a data entry format, but can 
          be adapted to any enviroment you run under.  For you
          programmers out there you can pass a parameter to 
          Dosbank and have it return a code, you can then in turn
          read that code back into your own program.  Details of
          this feature are described below.
        
          The program has a number of options from displaying a 
          message telling you if the card is good or not, as well
          as telling you what type of card it is, MasterCard, 
          Visa, American Express or Discover.

          Installation:

          "CCARD.EXE" (the main program), "LOAD.EXE" (Beginning 
          screen) and all other "DosBank" files can be put into
          the directory of your choice.  If you wish to run the
          program from anywhere in your system, you need to put
          that directory into your path.  For best results always
          run "LOAD" from the same directory ALL of the other
          files are in.  "LOAD" is NOT required for the program 
          to run properly, it only shows a PCX file and is a 
          prelude to "CCARD".
          
          Once you have completed the above DosBank is ready to go

          To start Dosbank you can run the "LOAD.EXE" startup 
          screen which will lead you into Dosbank, or you can run
          "CCARD.EXE" for an immediate entry into the program. 

          Instructions:

          1.  Entering a Number:  There are 2 ways to enter a 
              number into DosBank.  first you can just type it in
              normally and hit the <Enter> key and it will 
              validate that number.  Secondly, you can use your
              mouse and select the numbers individually by using
              the "Number Pad" provided with the program, and
              select the "Green" <Enter> under option one.

          2.  Verification:  Once you select <Enter> the program 
              will display the results of the verification.

              It will display a CYAN sreen with a message saying:
                 
                           Valid <Card Type> Number
              
              Card Type will either be Visa, Mastercard, American
              Express or Discover.  If the Card number did not 
              pass the validation process then you will get a 
              message saying:
                 
                         Invalid <Card Type> Number
              
              and the screen will turn red.

          3.  Command Line option:  You can pass a parameter to 
              Dosbank via the command line. Example:

                                "CCARD 6666666666666"

               "CCARD" being the program name, and 
               "6666666666666" being the Credit Card number.
               
               The Command Line option will return 1 of 5 
               different options, with 2 of those options the 
               Credit Card company will be displayed, those two
               options are Passed and Failed. The following are
               the result codes:

                        "1" -  Program Error:Can mean it was 
                               Program, User or Number produced

                        "2" -  Followed by Credit Card Type.  
                               This means the number passed 
                               validation process.

                        "3" -  Followed by Credit Card Type.
                               This means the number failed 
                               validation process.

                        "4" -  The number entered did not belong 
                               to a Major Credit Card Company.  
                               Could not process.

                        "5" -  Invalid Number:  Main cause of 
                               this error is length of number 
                               passed to program.  The number
                               should be between 13 and 16 
                               characters.

               The first character of the return code will always
               be a 1-5 so you can write your program accordingly.
               If the number passes or fails you can always count
               on the Credit Card company to be displayed along 
               with the result code.
               
               If you were to pass the number to DosBank from 
               the example above, the resulting code would be
               returned:

                                    "2 Discover"

               "2" Meaning passed, as described above, and 
               "Discover" being the Company that issued the 
               Credit Card.
              
              Program Information:

              This program was written in QuickBasic v4.5

              This Program was written by Joe Maguire, a 
              Programmer/Analyst for a Support company in
              Florida.

              Source Code Information:

              The source code is available and can be purchased
              while registering this program.  The Source code
              costs $67.95 (Including Registration), and 
              enables you to adapt the program to your specific
              needs.  In my example earlier, I've adapted it so
              I can call it and it will return a code to the 
              clipboard telling me whether it passed or not.      

              If you don't have a programmer on staff, or don't 
              have one that writes in QuickBasic. I can also 
              quote you on what I would charge to write it into
              your daily procedures for you.  Just notify me at
              the address above and I will contact you 
              immediately.  

              This program has also been written in Visual Basic
              for Windows,  and can purchased for the same 
              amounts as stated above. 

              Thank you for evaluating DosBank v1.0, I'm sure 
              you'll find it's everything you're looking for in 
              a quick Credit Card Validation utility for Windows.
