5.3 BASIC Program Input

5.3.1 Preparation

First, switch the power of the computer ON. At this time, the display should appear as
illustrated below.
This is the CAL mode, so the operation MENU 2 should first be performed to allow
input of BASIC programs. The display should now appear as illustrated below.
Note the BASIC indicator on the left of the screen indicates the BASIC mode. This is
the mode used for BASIC program input. The other indicators on tne display in the
BASIC mode have the following meanings.
P : Program area
0 – 9 : Program area numbers. The numbers of program areas which alreasy
contain programs are replaces by asteriks.
51146B : Capacity (number of bytes) remaining in area for writing programs and
data (free area). This number depends on the type of unit (FX-890P, Z1),
the presence of the optional RP-33 memory module, and will decrease
as storage space is used.
Ready P0 : Current program area = area 0. The current program area can be
switched by pressing Shift followed by the desired program area.
Previously stored programs can be deleted using one of two different procedures.
NEW : Deletes program stored in the current program area only.
NEW ALL : Clears all BASIC programs stored in memory.

5.3.2 Program input

The following input procedure inputs the sample program for calculation of the
volume of a cylinder.

Note that the . . key is pressed at the end of each line. A program line is not entered
into memory unless the .
ONE KEY INPUT
The one-key BASIC commands help to make program input even easier.
