Re: Source Grabber

You wrote my $length=length(@list); and this is completely wrong. You should have written my $length = @list; instead. Here's what you got: length() puts its argument in scalar context and evaluates it as a string. An array in scalar context returns the number of elements it contains. A number that's used like a string is converted to a string. length() returns the number of characters in its string. So if you had ten elements in the list, you were doing the equivalent of length("10") which is 2.

`BTW, the corresonding function to C<length()> is <scalar()> for a list (which forces scalar context, as already stated above).` `In case not already clear, this was meant for Andrew_Levenson.`	[reply]

`scalar()` for a list No. `scalar()` imposes scalar context for whatever expression is its argument regardless of whether that expression is a list, array, scalar, function call, etc. ⠤⠤ ⠙⠊⠕⠞⠁⠇⠑⠧⠊	[reply] [d/l] [select]
