I use the scalar keyword on occasion:
#!/usr/bin/perl
my @arr = qw/adfs adsf 4fd feqw3 f432d/;
print "The size of the array is " . scalar (@arr) . "\n";

The below is speculation since these questions need to be answered. In
addition to what is @files I'd add what is $Tmp?

Huh?

Sorry, it is an array I used above this block of code.

What are you
What are you trying to accomplish?
What is @files? Did you define it somewhere? Or is it a Perl global
var I don't know of?

I had the following code:
open (FILEOUT, "> $OutDir/info") or die $!;
print FILEOUT "text = abc\n";
my $Tmp = ++$#files;
print FILEOUT "moretext = $Tmp\n";
When I add the 3rd line, it initializes the files array and I can't use it
after? Why is that
I guess you could always dereference the array then find its size.
my(@sample, $ref, @de_ref);
# Original array.
@sample = ('sample', 'sample');
# Make reference to original array.
$ref = [EMAIL PROTECTED];
# De-reference the original array.
@de_ref = @$ref;
# Get the size from the reference.

I've got an array reference and I'm trying to figure out how many elements are in it. I've
tried '$#arrayref', '[EMAIL PROTECTED]', '$(@($arrayref))', and probably a few others that I've
forgotten. What is the correct way to do this?

Thank-you to everyone who answered my last question. As usually I am very
grateful for this group and the people in it.
Quick one.. is there a way to evaluate the size of an array? Right now I'm
writing the arrays to a file and then doing an "ls -l" to compare sizes. The
array is of type $array
