A non-executable statement that stores the numeric and string constants used by a program's READ statements.

Syntax: DATA {constant|EXECUTE(...)}[,...]
DATA my dog ate my homework, "oh, boy!", 34.4
DATA EXECUTE(LEFT$("Hello", 2, 3))

Constant is any valid numeric or string constant. If a string constant contains commas, colons, or leading or trailing spaces you want to preserve in your program, you must enclose the string in double quotes. You can also execute code by using the EXECUTE keyword. The return value of this executed code will be the value returned to your READ statement.
