Network using join command for files

Hi,
I have to join 2 files based on two key field columns.
But join command allows to give only one key column for fetching.So kindly update me whether i can compare 2 files based on two key columns or more than one key column.If so what is the syntax to compare it.
With thanks in advance,
subra.
