--- Comment #2 from Dominique d'Humieres <dominiq at lps dot ens.fr> ---
(dat(1:cn,n)) is not a variable, but an expression. Remove the enclosing
parentheses and your code will compile.

BTW the provided code needs a some more surgery in order to be compiled (dlc
not defines, iu, filecolumns, and filelines not typed).
