USAGE
   int scdwpack(
           int datafile,
           int *memofile );

PROTOTYPE IN
   sc_base.h

DESCRIPTION
   scdwpack will remove all memofile records which are not referenced
   by records in the datafile. The memofile will be compressed so
   that all active records will be contiguous after the pack. Files opened
   with the read only flag (SC_RDONLY) cannot be packed.

RETURN VALUES
   SC_SUCCESS   memo file packed successfully
   SC_MEMERR    memory allocation error
   SC_NOFILE    file not found
   SC_NOHNDL    no handles available
   SC_NULLPARM  parameter address NULL

EXAMPLE
   #include <softc.h>
   #include <sc_base.h>

   void main()
   {
     int dbf, fpt;

     scdinit(20,0);
     if (scddopenx(&dbf,"TOC.DBF",SC_SHARED) == SC_SUCCESS) {
       if (scddopenx(&fpt,"TOC.FPT",SC_SHARED) == SC_SUCCESS) {
         scdwpack(dbf, &fpt);
         scdwclose(fpt);
       }
       scddclose(dbf);
     }
     scdterm();
   }
