It
is
convenient
to
define the functions
of
special function keys
as
direct mode commands and
statements. However, numerical data and string data can also be assigned
to
these keys. The following
statement
assigns
the
character string "Personal
Computer
MZ-80B"
to
special function key 8.
DEF KEY (8)
= Personal
Computer
MZ
-80B
To
obtain
a listing
of
the
definitions
of
the
special function keys, execute the KLIST command.
When KLIST
is
executed, a list such
as
that
shown in Figure 2.17 is displayed.

FIGURE 2.17 List
of
special function keys
This list shows
that
special function keys I through 5 are defined
as
commands plus the I c R )
key; special function keys 6 through 8 are defined
as
data; special function key 9
is
undefined and
special function key
10
is
defined as KLIST I c R )
Labels are provided
to
enable
the
user
to
indicate
the
definition
of
each key
under
the
transparent
cover above each key.
These labels are useful when the same functions are assigned
to
the
special function keys every time
the
MZ-80B
is
activated.
