NEW
Format
Explanation
Example
NEW
The NEW command deletes programs in the BASIC memory area and clears pro-
gram
work
areas
such
as
the
variables
and
arrays.
When
the
BASIC
area
is
limited
with the LIMIT statement, the NEW command deletes only the programs in the
BASIC area; it does not delete machine-language programs.
10 INPUT A
20 PRINT A
30 END
When the above program is in memory, executing NEW will delete the program.
(Confirm the deletion by using the LIST command.)
NEW ON
Format
Explanation
NEW ON
Expands
the
BASIC
program
area
by
deleting
part
of
the
BASIC
interpreter
which
is
relating
to
the
plotter
printer
control.
This
command
can
be
used
only
when
the
optional
printer
(MZ-1P16)
is
not
used.
This
command
deletes
programs
in
the
BASIC
memory
area.
Example
NEWON
ccreaascawacsamece
Expands
the
BASIC
program
area.
CLR
Format
CLR
Explanation
Example
The
CLR
command
clears
all
variables
and
cancels
all
array
definitions.
All
numer-
ic
variables
are
cleared
to
0,
all
string
variables
are
cleared
to
null
strings
(‘
’’)
and
arrays
are
eliminated
entirely
by
nullifying
all
previously
executed
DIM
statements.
Therefore,
DIM
statements
must
be
reexecuted
to
redefine
the
dimensions
of any
required
arrays
before
the
arrays
can
be
used
again.
The CLR command also cancels all function definitions made with the DEF FN
statement;
therefore,
it
is
necessary
to
reexecute
DEF
FN
statements
to
redefine
such
functions before they can be used again.
The CLR command can not be included in a FOR ~ NEXT loop or subroutine.
10 A=12
20 B$ ="'parasol’’
30 PRINT A,BS
40 CLR
50 PRINT A,BS
60 END
The CLR statement on line 40 clears variable A to zero and BS to nulls.
