loop write variable to same file

Hi,

I try to loop write two dimensions variable to same filename, like:

opt = True
opt@fout = "foo.txt"

do i = 0, 10

write_matrix (a1(:,:), "2D18.10", opt)

end do

a1 is two dimensions variable by a1(x,2), x varies from i. The write_matrix only write last loop a1(10,2) to foo.txt. I think current variable a1 replace previous one. How to write total to same file?

Thanks,

cl
