DATA
Statement
DATA
constant [,constant,.
.
.]
Stores numeric and string constants
to
be accessed by a READ
statement.
This statement may contain
as
many
constants
(separated by
commas) as can
fit
on a line (a maximum of
255
characters in-
cluding the word DATA, commas, and spaces).
DATA statements may appear anywhere it is convenient in a pro-
gram. BASIC reads DATA statements sequentially, starting with
the first constant in the first DATA statement and ending with
the last item in the last DATA statement.
String constants containing delimiters, such as leading or trail-
ing blanks, colons, or commas, must be enclosed in double quota-
tion marks when used in DATA statements.
The data types in a DATA statement must match with the vari-
able types in the corresponding READ statement, otherwise,
BASIC displays a “Syntax error.”
Note that numeric expressions are not allowed in a DATA state-
ment.
To reread DATA statements from the beginning, use
a
RE-
STORE statement before the next READ statement.
