An open file can be reset back to the beginning. This might be useful if the file needs to be read twice. The rewind statement will reset the file read pointer and subsequent reads will start back at the beginning. The general form of a rewind statement is:
rewind(<unit number>)
Where the unit number was assigned during the initial open. The file must be open when the rewind is executed for the rewind to work correctly.
