I did many experiments, eval is for an old try and forgot to remove it for the
new change. Will remove it.

yes, you are right. Will remove it.

thanks for pointing this, I did not try all shells.
will replace it like your following patch did:
eval line='$line" "${'$index'}'

yes, there will be additional spaces to fill the 24 chars for each name. Will
remove with sed as your patch did.
