The eigenvalues are in the output: see the Model Summary Table (always displayed, even if /print none)

under the heading "Variance Accounted For", subheading "Total (Eigenvalues)".

Subject: Is there a way to get eigenvalues from CATPCA?

I am familiarizing myself with CATPCA.  Is there a way to have CATPCA produce eigenvalues so that I can can compare them to those from a PCA factor analysis of the same data.
I have 14 dichotomous variables coded 1 for no and 2 for yes. (CATPCA does not like 0,1.)
I have 51,000 cases.

So far I have this syntax what further specifications do I have to make?
catpca variables = vr46 to vr59
 /analysis = vr46 to vr59 (level=nume)
 /dimension = 3
 /plot = loading ndim(1,3)
 /PRINT = none.
catpca variables = vr46 to vr59
 /analysis = vr46 to vr59 (level=nume)
 /dimension = 3
 /plot = loading ndim(2,3)
 /PRINT = none.
