/* This program features : The display system time and date of the program is the main operation : the use of the system call dos function, importation case-D display the current date, case-insensitive T when the input output current system, when the input Q withdraw from the case-sensitive procedure, when losers in other characters, suggesting error. The main algorithm : the system date and time into the characters, sorting through the stack to show that involves strategically placed to coordinate conversion. The time and date shown only a call (functions) compute avoid code redundancy, make it simple as possible, and at the same time after the operation, the procedure waits for the next operation, rather than retire. The program showed multiple calls time display, in order to achieve dy
