OTOH I think he really wants `if (1 .. $not_default eq '') { do this ; }` [download] or even `if (1 .. !$not_default) { do this ; }` [download]	[reply] [d/l] [select]

Well, it's either `if (1 .. $not_default eq '')` or `if (1 .. $not_default eq "\n")` depending on whether he `chomp`s or not (if $_ is coming from a file as I suspect).	[reply] [d/l] [select]
