Bytes Free
The number on the second line of the screen, and before the words
"Bytes free", represents the amount of memory that is aval £i
e(in
BASIC.
The number is reduced each time a file is create
in
or TEXT mode.
When this number decreases to hundreds instead of thousands, be
very careful that sufficient memory is available for use.
ou s ou
delete any unneeded files, or save important files on an externa
device (a cassette tape).
The operations outlined in this chapter wi
require approximately 3000 bytes of free memory.
Be aware that certain BASIC commands, such as DIWI,
require extra memory in order to run the program.
Function Keys
There are five commands displayed on the bottom line of the screen
which correspond to the five Function Keys (f.l through f.5).
Press
the
Key and another set of five commands are displayed on
the screen.
These are the functions referred to as f.6 through f.10.
All of the ten Function Keys in the BASIC mode are different from
the
ten
in
the
MENU
mode,
so
do
not
confuse
the
two
modes.
Each
command
and its corresponding
function will
be
described later in this chapter.
