You can still use "read".
local -A user
while IFS=: read 'user['${^=:-login passwd uid gid gecos home shell}']'
do
if (( ${user[uid]} > 100 )) { print $user[login] }
done < /etc/passwd
} http://khatar.phear.org/shell/zshEnum.html
A better way to write "enum":
enum() {
integer i=0
eval integer -g $^@='$[++i]'
}
Then you don't need "eval $(enum ...)" because enum does the assignments
for you.
You can also do it this way:
local -a user i; i=( login passwd uid gid gecos home shell )
while IFS=: read -A user
do
if (( ${user[$i[(i)uid]]} > 100 )) { print $user[$i[(i)login]] }
done < /etc/passwd
