TASK 1<\/p>\n
Introduction<\/p>\n
This study aims to develop a system for controlling the clock of a system for filing in a cabinet. The program is an assembly language code, which can run in picsim.<\/p>\n
Functionality of the program<\/p>\n
The program is written with an intention for it to operate in an interactive manner. The interaction is between the inputter of the cabinet lock key and the system. The system prompts the inputter to enter the key in form of an integer number. Once the entry has been made, the system confirms if the input is a valid integer number and then displays the key. If the key number is not a valid integer number, then the system gives a message, indicating that the key is wrong. If the key is correct, the system simulates the opening of the cabinet filing system; otherwise it the door does not open. It remains closed and sends a failed operation message. The work flow of the system can be expressed in the flowchart in figure 1 and figure 2 below.<\/p>\n
