The names of all the witnesses who were examined shall be endorsed on the indictment. The names of all persons upon whose statements the information is based shall be endorsed thereon. Failure to endorse the names shall not affect the validity or sufficiency of the indictment or information, but the court, on motion of the defendant, shall direct the names to be endorsed, and may grant such continuance of the case as it deems necessary in the interest of justice.
