READ
Abbreviation: R <SHIFT+E>
TYPE: Statement
FORMAT: READ <variable>[,<variable>]...
Action: The READ statement is used to fill variable names from
constants in DATA statements. The data
actually read must agree with the variable types specified or
the BASIC error message ?SYNTAX ERROR will result.(*) Variables
in the DATA input-list must be separated by commas.
A single READ statement can access one or more DATA
statements, which will be accessed in order (see DATA),
or several READ statements can access the same DATA
statement. If more READ statements are executed than the number
of elements in DATA statements(s) in the
program, the BASIC error message ?OUT OF DATA is printed. If the
number of variables specified is fewer than the number of elements
in the DATA statement(s), subsequent READ
statements will continue reading at the next data element. (See
RESTORE.)
*NOTE: The ?SYNTAX ERROR will appear with the
line number from the DATA statement, NOT the READ statement.
EXAMPLES of READ Statement:

120 DATA 1,2,HELLO
100 FOR X=1 TO 10: READ A(X):NEXT
200 DATA 3.08, 5.19, 3.12, 3.98, 4.24
210 DATA 5.08, 5.55, 4.00, 3.16, 3.37
