The latter is preferred over the former. Regards, Cory Please see FAQ731-376 for tips on how to make the best use of Eng-Tips Fora. Upvote 0 Downvote

I have the right spec number at work but our IT Dept blocks people from posting from there. Imagine that: employees participating in public forums share and give knowledge with his peers! We'll have none of that! Tunalover Upvote 0 Downvote
