1. GENERAL:  The Enigma95 Cipher Machine uses the following files:

   a. Main Operating Program : ENIGMA95.BAS which is explained by:

      (1) ENIGMA95.DOC - A text discussion of what it is and how it operates.

      (2) ENIGMA95.FLO - A flowchart of the operation.


   b. Data Files:  The changeable components of the machine:

          File Name     Created By    Text File     Creates
          ------------  ------------  ------------  -------------------------
      (1) ROTORS.DAT    CRYPTO27.BAS  CRYPTO27.DOC  Regular Rotors

      (2) REVROTRS.DAT  CRYPTO34.BAS  CRYPTO34.DOC  Reversing Rotors

      (3) CHARS.DAT     CRYPTO30.BAS  CRYPTO30.DOC  Character Sets

      (4) CODE.DAT      CRYPTO28.BAS  CRYPTO28.DOC  Super Encipherment Tables


   c. Programs which support and contribute to the understanding of ENIGMA95:

      (1) CRYPTO05.BAS - A Random Number generator for input to b(1) and b(2).

      (2) CRYPTO43.BAS - A graphic demonstration of ENIGMA95 internal operation.

      Each of these program files have matching .DOC files that explain them.


   d. CRYPTO45.BAS is a program to scan ROTORS.DAT for matching values in the
      at the same position within the rotors in the set.  It is a coincidence
      test.


2. The .BAS files are program files meant to be run by QBasic or QuickBasic
   by inserting the disk into the B Drive and typing the following command at
   the C prompt:
                  QBASIC /RUN B:ENIGMA95.BAS <enter>
              or
                  QBASIC /RUN B:CRYPTOxx.BAS <enter>

   The " xx " is one of the following: 05, 27, 28, 30, 34, 43, or 45.

   

3. The .DAT files are meant to be on the same B Drive disk to be used by
   ENIGMA95.BAS which would be loaded from another disk and be active in the
   computer.


4. The .DOC and .FLO files are text files meant to be read by switching to the
   B Drive and using the command at the B prompt:

                  TYPE filename.ext |MORE <enter>


5. PROCEDURE FOR STARTING A PROGRAM:

   a. Be at the C prompt and insert the Enigma95 Disk. Make sure the write
      protect window is active (open).

   b. Type QBASIC <enter>.    Be at the "Welcome" panel.

   c. Press "Esc" key.        Be at the blank untitled window.

   d. Press "  ALT + F + O " keys in succession.   Be at OPEN window.

   e. Press "Tab" 2 times to go to Dirs/Drive Box.

   f. Press "down arrow" until Drive B  [-B-]  is selected.

   g. Press <enter>.

   h. See program files on B disk in OPEN window.

   i. Press "Tab" to go to FILES Box.

   j. Press "down arrow" to select the program file.

   k. Press <enter> to sctivate the program.

   l. See the program listing.

   m. Press " ALT + R + S " to run the program.


6. PROCEDURE FOR STOPPING AND EXITING PROGRAM:

   a. Press <ctrl> and <break> keys to stop and return to the program listing.

   b. Press " ALT + F + X " to exit QBasic and return to the C prompt.
