I tend to agree. However, this poster was not using functions. He was simply declaring 'our' every time he saw the variable. That's why I told him to move the declaration of 'our' to the top. The reason he "had to" keep declaring 'our' is that he was only declaring it in the insanely small scope of the actual expression. There is no need for that. Just declare it before the big block of code that uses it. Paul Lalli -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] http://learn.perl.org/
