bad name on a commented out line

justin423 has asked for the wisdom of the Perl Monks concerning the following question:

I have never seen this before. here is the code. use Term::ReadKey; ReadMode('noecho'); $tbpass = ReadLine(0); I am getting this message: Bad name after noecho' What is even weirder is that i get it even when it is commented out with a "#". is this because there is a single ' higher in the code?

is this because there is a single ' higher in the code? If your code looks something like this: `my $unterminated_single_quote = '<-- this is not terminated; use Term::ReadKey; ReadMode('noecho'); $tbpass = ReadLine(0);` [download] then yes. Single-quoted strings can contain embedded literal newlines (update: i.e., single-quoted strings can be multi-line strings). Update: Please see Quote and Quote-like Operators and Quote-Like Operators in perlop. Give a man a fish: `<%-{-{-{-<`	[reply] [d/l] [select]
