DATA¶
Syntax¶
Purpose¶
To store the numeric and string constants that are accessed by the program's READ statement(s).
Remarks¶
DATA statements are nonexecutable and may be placed anywhere in the program. A DATA statement may contain as many constants as will fit on a line (separated by commas), and any number of DATA statements may be used in a program.
The READ statements access the DATA statements in order (by line number) and 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.
<list of constants> may contain numeric constants in any format, i.e., fixed point, floating point or integer. (No numeric expressions are allowed in the list.)
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.
The variable type (numeric or string) given in the READ statement must agree with the corresponding constant in the DATA statement.
DATA statements may be reread from the beginning by use of the RESTORE statement.
Example¶
10 DATA 12, 3.14159, "Hello", WORLD
20 DATA "Smith, John", 100, -5.5
30 READ A, B, C$, D$
40 PRINT A; B; C$; D$
50 READ NAME$, SCORE, ADJUSTMENT
60 PRINT NAME$, SCORE, ADJUSTMENT
