Simple question about "whiles" and files...

[Sebadamus]

Does anybody knows why I cant make this to work as I want? :-)

while (<ARGV> and  $_!=~/End of list/)
{
    bla
    bla
    bla
}

So, with this I want to process the file in <ARGV> until EOF, and each line
must be distinct than "/End of list/".  So, if it is EOF or the current line
is that string... the WHILE should exit...

Can anybody HELLLLLPPP me...?

Thanks you very much,

Sebastian.
