Stores numeric and string constants to be read with the READ statement.
DATA
constant [ ,constant]…
constant is a numeric or string constant.
String constants in DATA
statements must be surrounded by double quotation marks only if they contain commas, colons, or significant leading or trailing spaces. Otherwise, quotation marks are not needed.
READ statements access the DATA
statements in order. The data contained therein may be thought of as one continuous list of items, regardless of how many items are on a line or where the lines are placed in the program. The variable type (numeric or string) given in the READ statement must agree with the corresponding constant in the DATA
statement, or a Type Mismatch
error occurs.
DATA
statements may be reread from the beginning by use of the RESTORE statement.
You can only use data statements at the module level, never in a procedure.
FOR I=1 TO 10
READ A(I)
NEXT I
DATA 3.08,5.19,3.12,3.98,4.24
DATA 5.08,5.55,4.00,3.16,3.37
This program segment reads the values from the DATA
statements into array A
. After execution, the value of A(1)
is 3.08
, and so on. The DATA
statements (last two lines) may be placed anywhere in the program; they may even be placed ahead of the READ statement.
PRINT
PRINT "CITY","STATE","ZIP"
READ C$,S$,Z
DATA "NORTH RICHLAND HILLS,","TEXAS",76182
PRINT C$,S$,Z
CITY STATE ZIP
NORTH RICHLAND HILLS, TEXAS 76182
This program reads string and numeric data from the DATA
statement.
