Hi,
I have a snippet of code as below.
Even when I return 0 or '', why does @blocks evaluate to true?
If rows returned are 0, then if(@blocks) should evaluate to false, correct?
Thanks,
Radhika

use strict;
use diagnostics;
my @blocks = ();
sub do_something
{
my @row = @_;
return @row if(@row);
return '';
}
@blocks = do_something();
if([EMAIL PROTECTED])
{
print("Got this number: @blocks\n");
}
else
{
print("Got nothing\n");
}
