Hi perlsyntax,

Looks like you forgot to use code tags in your post. The code you have provided does not mention mem but three variables containing the string mem do exist ($mem1 $mem2 and $mem3), however in the code you have provided we can not see what is assigned to them. Perhaps reading How do I post a question effectively? then updating your post would help.

Update: The question has now been changed, my post is now out of context.

Thanks

Martin
