Errors
If you get a
Transmit ERROR!
message, check each calculator to be sure the
link cable is pushed all the way in and try again. Remember that after you
arrow to the program or list you want to send, you must press
(SEL)
to
select it to transmit. Also, the receiving calculator must be
Receiving
before
the sending calculator transmits. If the receiving calculator already has
a program or list by the same name as the one you are sending, the
sending calculator will ask if you wish to overwrite the item on the other
calculator. Select
(YES)
to overwrite or
(NO)
to skip transferring
that item.
Note 0G • Entering a Program
Your calculator is like a small computer. You can instruct (or program) it to
do calculations or to communicate with other devices. What follows is not
instructions on how to write a program, but instructions on how to enter a
calculator program that has already been written. You must be very careful
to enter the commands exactly as they are written. Changing the program in
any way will alter how it runs and may cause an error.
There are three ways to enter a program into your calculator. Two easy ways
are to download a program from either a computer or another calculator. To
use a computer, download the program from a CD-ROM directly into your
calculator by using the Casio Program-Link™ software. To use another
calculator that has the program in its memory, link the two calculators with
a link cable and transfer the program. (See
Note 0F.
) The third way to enter
a program is to do it manually by following the steps below:
a.
Select
PRGM
from the Main Menu.
b.
Press
(NEW)
to name the program. (Use the red letters above the
number and operation keys.) You are already in Alpha Lock, so do
not press
unless you want to enter a number in the program
name. When the name is complete, press
.
c.
Enter the program exactly as you see it. Lowercase letters in the
command indicate that you must find the command on the
calculator. You can find many programming commands by pressing
[PRGM]
and looking under
COM
,
CTL
and
JUMP
. The key
will
often give you more options. Use the function keys to access the
commands shown at the bottom of the screen. To find other
commands, press the appropriate function key or look at the
function options by pressing
[SET UP]
