The

RUN

mode is a very versatile operation mode, which allows

calculations and operations available

in

the Organizer CALC mode, and

in the

AER

and STAT modes, calculations using results from the STAT

mode, and has the ability

to

run

BASIC programs written in the PRO

mode.

the system "hangs up" (you cannot get it to respond at all), refer

to

the

Organizer Operation Manual to clear the error. Pressing the

operations.

You

•

Recalling a formula after execution will cause a value such as "5E3"

or "5E-3" to be displayed

as

"5000" or "0.005". A value such as

"5.000" will be displayed

as

"5"

. If the value

SHIFT

I (or

2nd

F )

and

~

(t)

keys will toggle the

beep sound for key entry.

tting the beep while in the BASIC mode

is effective for other operation modes.

•

The Card has an 8 byte input buffer to hold up to 8 key entries

while a computation is being performed.

• 8

bytes are used for a numeric value in single-precision mode while

13 bytes are used in double-precision mode. It

is

not always

possible to store up to 254 characters in one line.

Simple Calculations

The Card performs calculations

in

the RUN mode with 10-digit

precision (unless set to the double-precision mode, which will be

discussed later).

Turn the power

on

and try these simple examples.
