recording eigenvalues

I have the eigen command working now.
But it won't record the eigenvalues.
I've been looking at the manual (p. 228, 229) and that doesn't record my eigenvalues. It does record the reactions if I put the nodes and dofs into the command. For example:

recorder Node -file Q4.out -dof 1 eigen

This gives me the reactions for the four nodes in dof 1.
Similar things happen when I put in "-dof 2 eigen" or
"-node 1 -dof 2 eigen" etc. I just get the appropriate reactions.

What's up with this?

Try:

recorder Node -file eigen1.out -node all -dof 1 2 3 "eigen 1"

with the brackets around the "eigen #" portion
