When are pressed,the system mode changes to
the WRT mode.Then,the number of remaining steps is
indicated.The number of remaining steps is decreased
when programs are input or when memories are expanded.
If no programs have been input and the number of
memories equals 26(the number of memories at
initialization),the number of usable steps should equal 400.
The larger figures located below indicate the program
areas .If the letter "p" is followed by the numbers 0 through
9,it indicates that there are no programs stored in areas P0
through P9.The blinking zero here indicates the current
program area is P0.
Areas into which programs have already been stored are
indicated by"_" instead of numbers.
Here the previously mentioned program will be stored to
program area P0 (indicated by the blinking zero):
With this unit,the operations performed for manual
calculations can be used as they are in a program.Once
program execution starts,it will continue in order without
stopping.Therefore,commands are required to request the
input of data and to display results.The command to
request data input is "?",while that to display results is " " .
A "?" within a program will cause execution to stop temporarily
and a "?" to appear on the display as the unit waits for data
input.This command cannot be used independently,and is
used together with as memory name".
To store a numeric value in memory A,for example:
? A
When "?" is displayed,calculation commands and numeric
values can be input within 127 steps.
The command causes program execution to stop
temporarily and the latest formula result or alphanumeric
characters and symbols to be displayed.
This command is used to mark positions in formulas where
results are to be displayed. Since programs are ended and
their final results displayed automatically,this command can
be omitted at the end of program.However,if the BASE-N
mode is specified for base conversion during a program,do
not omit final " ".
Here these two commands will be used in the previously
presented procedure:
Now the program is complete.
Program storage
The storage of programs is performed in the WRT mode
which is specified by pressing
.
