sortqq problem

$

0

Can anyone explain why the following program does not work? All but the first element of array lar2 are truncated to the lower 32 bit by sortqq. That's independent of compiler version and the inclusion of a "use ifport" statement.

      use ifport

      implicit none

      integer*4 i,mod,iflag,size

c      integer*4 irand

      integer*4 iaux

      integer*8 lar2(15),count,adrarray

     

      iflag=1374

      i=mod(irand(iflag),15)+1

      iflag=0

      do i=1,15

        iaux=mod(irand(iflag),15)+1

        lar2(i)=iaux*2_8**32+i

        write (*,*)  lar2(i)   

      end do

      adrarray=loc(lar2)

      count=15

c      size=Z'00060000'

      size=SRT$INTEGER8

      write (*,*) adrarray,count,size

      CALL SORTQQ (adrarray,count,size)

      write (*,*) adrarray,count,size

      write (*,*) 'After sort:'

      do i=1,15

        write(*,*) lar2(i)

      end do

     

      stop

      end
