<DIV>I have an apparently very simple problem.</DIV>
<DIV> I have correlation data cor(i,j) over an xy domain. Using a fortran program I have written the data into binary to display in Grads. Apparently Grads is able to open the data file.</DIV>
<DIV>when I put recl=4*l, the display is blank (with only map of Africa of course)</DIV>
<DIV>when I put recl=8*l, the display says constant field value=0.</DIV>
<DIV> </DIV>
<DIV>Here are snippets from my fortran program:</DIV>
<DIV> </DIV>
<DIV> open (10,file='zcor824.dat',form='unformatted',access='direct', recl=4*(l+1))<BR> </DIV>
<DIV>irec=0<BR> do k=1,m<BR> irec=irec+1</DIV>
<DIV> write(10,rec=irec) (cor(i,j),i=1,l)<BR> enddo</DIV>
<DIV> </DIV>
<DIV>and my ctl file</DIV>
<DIV> </DIV>
<DIV>dset zcor824.dat<BR>undef -1.00E+09<BR>title correlation<BR>xdef 55 linear -30 1.5<BR>ydef 57 linear -42 1.5<BR>zdef 1 levels 850<BR>tdef 999 linear 00Z29AUG97 6hr<BR>vars 1<BR>cor 1 99 linear correl coeff<BR>endvars</DIV>
<DIV> </DIV>
<DIV>Any help would be very welcome to resolve my problem</DIV>
<DIV>Thanks all.<BR></DIV><BR><BR><p>
