;TicGo==========Set and start timer.
;C Function prototype: char TicGo(char cHr, char cMin, char cSec, char cHth);
;Description of Function: Sets hour, minute, second and hundredths and starts TIC.
;User interface: Set the 4 parameters to the required time.
;		Call TicGo function.
;		TicGo sets the start time and starts the timer.
;		returns TIMECON (guaranteed not zero).
