Timers.pas intercepts the IBM PC timer interrupt $1C and allows you
to write Pascal routines which will be executed every 55 ms. Be careful not
to write any routines which will take over 55ms to execute.


NOTE - These routines alter the IBM PC interrupt vectors. Be sure
to call InitTimerInterupt only once and be sure to call ReleaseTimerInterupt
only once at the end of your program.
