;
;IT IS INVOKED WHENEVER A PAGE OVERFLOW WOULD HAVE HAPPENED.
;
;
;ACCORDING TO THE PROPOSED STANDARD, ALL SOURCE FOR A ROUTINE
;MUST OCCUR ON ONE PAGE. HOWEVER, IT IS IMPORTANT FOR THE
;USER TO FIND "SENTENCE" BREAKS TO FORM THE OVERFLOW (EJECT)

;TO THAT EFFECT SHOULD APPEAR IN THE LISTING. ALL THIS IS
;ACCOMPLISHED BY THE USER INCLUDING THE MACRO "CONT." IN HIS

;END OF THE TEXT ACCUMULATED SO FAR:
; INFO. REDEF.,"SAMPLE LINE"
