Complex Eval

I wanted to extract the low order 2 digits of the year value in an *iso
date field. Trying to do the most in the shortest possible instruction, I
entered:

D iso_date s d

eval pr_year = %dec(%subst(%editc(%subdt(iso_date:*y):'X'):3:2):2:0)

iso_date contains '2007-06-16'
pr_year is a 2-byte numeric (whole number) field

After the 'eval', pr_year contained 00, not 07. I figured I'm not
understanding something about the step-by-step nature of complex
statements. My first workaround attempt involved extracting the innermost
evaluation and doing it separately (fscl@yr is 4,0):

eval fscl@yr = %subdt(iso_date:*y)
eval pr_year = %dec(%subst(%editc(fscl@yr:'X'):3:2):2:0)

This worked fine. Anybody (or everybody) know why the first 'eval' didn't
work? Thanks.
