(1)Where under the provisions of section 396 or 400 of this Act a court is required to state a special reason for its decision or the grounds on which it is satisfied that it is undesirable or impracticable to place an offender under supervision, the reason or, as the case may be, the grounds shall be entered in the record of the proceedings along with the finding and sentence.
(2)Any reference in the sections last mentioned to imprisonment shall be construed, in the case of an offender on whom by reason of his age imprisonment may not lawfully be imposed, as a reference to the lawful form of detention in default of payment of a fine appropriate to that person, and any reference to prison shall be construed accordingly.
