    00011  *     reorgainized to put the format-specific header items in *head.h
    00012  *     and the putaway-specific items in *putaway.h, of which there
    00013  *     currently is only sacputaway.h
    00014  *     Function protoypes used by putaway.c moved to pa_subs.h
    00015  *
    00016  *     Revision 1.2  2000/03/09 21:54:36  davidk
    00017  *     Added function prototypes for the ah putaway routines, so that
    00018  *     users of the ahputaway routines would not get compile warnings.
