Purpose:  Displays current time and date when hot keys are pressed.

DOS RAM:  About 9k if expanded memory (LIM specification) is present.

Requirements:  DOS 3 or higher and a color graphics adapter (CGA).



Method:

  DCLOCK is  loaded by  typing its name at the DOS prompt.  Thereafter it can
be called by pressing Control-LeftShift-T.    The  default  position  for the
display is  the upper  left corner,  but it  can be moved with the Home, End,
Page Up, Page Down, and arrow keys to any position on the screen.  It will be
in the  new position  when the program is called again.  Pressing H while the
clock is displayed brings a help screen in exactly the  same position  as the
time/date display  box to  remind you  of what the positioning and other keys
do.    Pressing  any  key  then  returns  the  time/date  display.    Time is
continuously displayed  to the  tenth of  a second, the main time numbers are
about 1 inch high,  and the  color changes  at 0  and 30  seconds.   The date
includes the day of the week, month by name, day of the month, and year.

  Pressing ESC causes the program to terminate and stay resident for the next
press of the hot keys.  Pressing F10 will terminate  the program  and release
the memory it occupies, provided no program has been loaded after DCLOCK.  If
the program can't be ended and memory released, a message  to that  effect is
displayed and  the program  terminates and  stays resident instead.  You will
have to remove the programs loaded after DCLOCK before you can terminate.
