2. 3. 5. 6 RESTORE (abbreviated format: . . . RES.)
RESTORE or RESTORE Ln
When READ statements are executed, a pointer managed by the BASIC interpreter
is incremented to keep track of the next item of data to be read from DATA state-
ments. The RESTORE statement resets this pointer to (1) the beginning of the
first DATA statement in the program or (2) the beginning of the DATA statement
on a specified line.
