Re^2: reading file into an array

Sorry, it starts on line 15. Thanks for the reply. It is working now. And I like your way of the while loop much better than what I used. However, I'm new to perl and don't fully understand your for loop. I assume the "13 .." just means start at 14 but why is there a '#' in front of the fileContents and why $ instead of @? Java was my first language so perl is very different and its taking a lot of getting used to. Thanks for the replies!

Re^3: reading file into an array by McDarren (Abbot) on Dec 05, 2008 at 21:52 UTC
$# (not #$) refers to the index of the last element of an array. The "at-sign" sigil (@) is used when you refer to two or more elements of an array. If you are accessing (or referring to) a single element of an array, then the "dollar-sign" ($) sigil is used. For example: `my @foo = qw/a b c/; print "$foo[1]\n"; # Prints b print "@foo\n"; # Prints a b c print "$foo[$#foo]\n"; # Prints c (but you would probably never do th +is) print "$foo[-1]\n"; # Also prints c (a better way than the previou +s) print "@foo[0,2]\n"; # Prints a c` [download] Cheers, Darren :)	[reply] [d/l]

For an array `@array`, `$#array` gives the index of the last item in the array. It's a minor piece of cryptic Perl syntax. G. Wade	[reply] [d/l] [select]
