CHAPTER 7 Command Reference
RETURN
Function:
Provides a return from the subroutine to the main program.
Explanation:
Returns to a statement located just after the statement which called the sub-
routine.
Branch

[Branched
location]

No.
* Branched location { # program area No.
Function:
Branches to a subroutine according to a branch condition.
Parameter: :
Branching condition: Numeric expression.
Values below the decimal point are discarded.
Line No.: 1 to 9999.
Program. area No.: Oto 9.
Explanation:
1)
Performs
a
subroutine
branching
by
the
integer
part
of
the
value
in
a
branch
condition
expression.
Branched
locations
are
allocated
sequentially
according
to
the
value
of
the
expression.

ast Baz B=3
2)
When
the
value
of
the
expression
is
smaller
than
1
or
an
appropriate
branch-
ing
location
does
not
exist,
the
next
statement
is
executed
without
branching.
3)
As
many
branching
locations
as
can
fit
in
one
line‘can
be
written.

Function:
Stores data.
Parameter:
Data:
Character
constant
or
numeric
constant.
Explanation:
1) Used to write data that is read by a READ statement.
2) Plural data can be written by punctuation with “,”.
3)
If
only
a
DATA
statement
is
executed
without
a
READ
statement,
no
func-
tion
is
performed.
4)
When
a
character
constant
includes
“,”,
place
it
inside
“
”.

5)
When
data
is
omitted,
a
character
string
with
a
length
of
0
is
taken
by
default.
DATA’A, ,B — DATA A,*”,B
DATA , — DATA *”,*” —>— Null string

6)
Even
if
a
command
is
added
to
a
DATA
statement
with
a
colon
(:),
it
will’be
regarded as data and will not be executed.
