WHAT IS THE POP CLOCK PROGRAM
Pop Clock is a memory resident program for the PC/XT/AT that allows the
user to display (pop-up) the time in the upper right hand corner of the
screen. The program also allows the user to set an alarm to beep at one
of two tones for a given time.
Pop Clock was designed as advertising promotion and may be freely
distributed in its original form with its original documentation by
anyone that wishes without prior consent from:
Tulk Associates Software
Personal Computer Services
13791 De Foe Ave. Sylmar, CA 91342
(818)367-4127
INSTALLATION
To install the Pop Clock program simply enter PCLOCK at the DOS prompt.
The program may also be installed via the AUTOEXEC.BAT or other batch
file if the user so desires (see Batch Commands in your DOS manual).
The program is self-checking to ensure that it is not installed more
than once, but the method of checking for prior installation may be
disrupted by the installation of other memory resident program(s) after
Pop Clock has been installed.
A WORD ABOUT MEMORY RESIDENT PROGRAMS
The order of installation of any memory resident program is always an
iffy situation. Every attempt has been made to ensure that the Pop
Clock program behaves in a predictable fashion. If you are using other
memory resident programs you may need to experiment with the order in
which they are loaded. We suggest that you load Pop Clock first if you
want to call the clock from within other resident programs otherwise
Pop Clock may be loaded last.
Some applications behave poorly when memory resident programs are
installed or when they are used at the same time. If any of your
application programs (word processor, etc.) do not function properly
remove the memory resident program and reboot the system. We suggest
that you use the memory resident program at the start of an application
to insure that it coexist properly with the application.

HOW TO USE POP CLOCK
Whenever the clock is called to the screen an instruction bar will
appear on the 24th line of the screen. This instruction bar lists all
of the keys used in Pop Clock. For first time users the instructions
are explained below.
TO ACTIVATE THE CLOCK simply press the ALT T key combination and the
clock will appear in the upper right hand corner of the screen. To
deactivate the clock and continue with what you were doing press the
ESCAPE key.
TO SET THE TIME call up the clock as described above. Press the F1
function key. The word TIME will appear on top of the clock and the
hour will start to flash. To change the hour use the arrow keys to
increase (up arrow) or decrease (down arrow) the time by the desired
amount. Hit the RETURN key and the minutes will start to flash, when
minutes have been set hit the RETURN key again. The time is now set.
TO SET THE ALARM call up the clock as described above. Press the F2
function key. The word ALARM will appear on top of the clock and the
hour will start to flash. To change the hour use the arrow keys to
increase (up arrow) or decrease (down arrow) the time by the desired
amount. Hit the RETURN key and the minutes will start to flash, when
minutes have been set hit the RETURN key again. The alarm is now set.
TO TURN ON THE ALARM call up the clock as described above. Press the
F3 function key a musical note will appear under the time. The alarm
is now on.
TO SELECT A TONE call up the clock as described above. If the alarm
is not on (note under time is not displayed) press the F3 function
key to turn it on. Press the F4 function key and the musical note
under the time will change from a single note (low tone) to a double
note (high tone). The tone is now selected.
TO TURN OFF THE ALARM calling up the clock as described above while
the alarm is sounding will shut it off. If the clock is on the screen
when the alarm sounds the F3 function key will shut it off. The alarm
will turn off automatically after one minute.

HOW TO CHANGE THE HOT KEY USING DEBUG
You may find that the specified POP CLOCK Hot Key (Alt T) conflicts
with other software usage. If this should be the case you may change
the POP CLOCK Hot Key value using the DOS Debug program.
The example shown below will change the value of the Hot Key from
Alt T to Alt Z. The information within the [ brackets ] is displayed
by Debug. The response text is normal and the *text are comments.
A> debug pclock.com *load pclock.com into the
*debug program and dump the
[-]d 104 l2 *current hot key value, a
*two byte code, 1st byte
[nnnn:0104 14 00] *is auxiliary value and
*2nd is the scan code.
[-]e 104 *edit the auxiliary byte
*value by replacing it
[nnnn:0104 14.]2C *with the value for the
*new key (Alt Z here)
[-]n pclock.com *just to be safe, make
*sure the name is still
[-]w *pclock.com, and write
*the file back to disk
[writing 0C42 bytes] *confirm that all bytes
*have been written and
[-]q *quit the debugger
Please note the the program messages will still indicate Alt T as the
Hot Key. If you wish to change them you may. Use the same procedure
as above for locations nnnn:0CCC & nnnn:0D31 replacing each byte with
the ASCII value of the new character (in hex).
The following auxiliary byte hex values may be used to produce the
Alt key combinations for their associated letters:
hex key hex key hex key
value value value value value value
