TAPE CONTROL
When the BASIC interpreter or another system program is started, keyboard operation is automat-
ically set in the normal mode. Alphanumeric characters and symbols are input in the normal mode.
For example, to input a B, press the
0
key (See Figure 2.1 0) in the same manner as on an ordinary
typewriter. Note that the letter keys normally produce capital letters. To enter lower case letters, hold
down the [
SHIFT
/key then press the letter key- just the opposite of an ordinary typewriter.
The reason for this is that capital letters are generally easier to read on the screen, so most people
prefer to write their programs in capital letters. When a key has two non-alphabetic symbols on it,
such as []] (above the
0
key. See Figure 2.10.), pressing the key alone enters "8". If you hold
down the
I
SHIFT /
key while pressing []] , "(" will be entered. Only the 26 letter keys are shifted
in the opposite direction from a standard typewriter.
t
The
[sFT
LocK/ key locks the
I
SHIFT /
key so that it does not need to be held down. When the
SHIFT /
key is locked, the
lsFT
LocK/lamp (See Figure 2.1 0) lights and pressing the
0
key inputs
"b". Characters and symbols which can be input in the normal mode correspond to ASCII codes 20H
to 7EH. (See Figure 2.22, ASCII code table.)
t
The BASIC interpreter SB-5 510 and DISK BASIC interpreter SB-651 0 are provided with the CHANGE statement.
With this statement, the shift direction of the 26 alphabetic characters, A to Z, entered from the keyboard can be
changed.
