Using associative arrays in zsh (or ksh or maybe bash?) you can write
typeset -A to_archive
to_archive=(z_bak 7 root 14 y_spam_definite 56)
for mydir in ${(k)to_archive}
do
mydays=$to_archive[$mydir]
But I've actually never used them before doing this, and I have to say
the ${(k)to_archive} is beyond my current tolerance for shell wierdness.
