README.txt

Following is a brief description of the associated ABM project implementation.

The source files are generic C, and should compile with any C compiler.  A makefile is provided for those using GNU tools.

The initial database that the system uses is loaded through an initialization file, by default called "mydatabase.txt".  The example initialization file included with this distribution has a header with the syntax that should be used within the file.  The name of the database initialization file may be changed by modifying the constant in constants.h.


Basic operation of the ABM:
The initial menu is an overall system-level interface, which is higher than a user or operator interface.  This menu allows a card to be swiped into the system, the operator to switch the operator key, and for the day to be incremented.  By choosing to swipe a card, access is granted to the system user interface, and by switching the operator key, the operator interface becomes accessible.  Exiting from the high level menu causes the ABM software to terminate, which is again a higher level function than the user interface functions.


The source files are as follows:

check_balance.c		- Routines to handle check balance transactions
deposit.c	- Routines to handle deposit transactions
main.c		- Primary synchronization code, and highest level menu
transfer.c	- Routines to handle transfer transactions
database.c	- High level access routines to use the database component
getch.c		- Getch() emulation code for GNU targets
operator_interface.c	- Operator interface module
user_interface.c	- Portions of the user interface module
databaseInit.c	- Initialization routines for the database - database component
linklist.c	- Low level routines of the database module
screen_output.c	- Screen output routines - part of user interface module
withdraw.c	- Routines to handle withdrawal transactions
