in thread Removing blank lines from array

I am intrigued greatly by jjohns solution to my problem but i dont't understand when he set up his while loop using 
while(my $line = )

the loop has no condition, won't that give you an error

    I guess it was a typo. The proper line would read: 

      while(my $line = <READ>)
    Maybe jjohn forgot to type the angle brackets as ampersand HTML entities (&lt; and &gt;), he just typed the single characters, and your HTML renderer has considered it was a tag, and an invalide one, and discarded it.

    He probably used <pre> instead of <code>...

      All true! I forgot about <code> and those durn HTML entities. In a few more years, I get the hang of this "web" thing I've heard so much about. :-D
