May i know if the below code is added , will it set all the rest of the base array index to 1 or does it just apply to the particular array @Marks only ?
Another question is that my "reports_${counting}_${_[0]}.txt" file has the below contents, however if i put the index to be the below in red, i would NOT be able to capture the correct $lotsuffix variable ? Why is this so ?
hi
this is an example of code:
use strict;
use warnings;
open FILE, "/tmp/result_2";
my $regex="\\ Starting program ver. (.*)";
my $res="Program started, version <$1> - OK.\n";
while (<FILE>) {
if ($_ =~ /($regex)/) {
print "$res";
}
}
close FILE;
This finds $regex and print... (3 Replies)

I feel that i am missing something obvious but i can't find what is wrong.
I have a script that is launching some functions with "&" and each call is feeding the array with a value. When all calls are finished I just want to retrieve the values of that array.
It is looking like that :

Hi all,
a question for the Perl knowledgeable:
I have use warnings; enabled.
I use something like:
($sec,$min,$hour,$mday,$mon,$year,$wday,$yday,$isdst) = localtime(time);
In the further code I only work with some of the returned variables, as the others I have no need for.
Though the... (1 Reply)

Perl::Critic::Policy::Variables::RequireNegativeIndices(User Contributed Perl DocumentatPerl::Critic::Policy::Variables::RequireNegativeIndices(3)NAME
Perl::Critic::Policy::Variables::RequireNegativeIndices - Negative array index should be used.
AFFILIATION
This Policy is part of the core Perl::Critic distribution.
DESCRIPTION
Perl treats a negative array subscript as an offset from the end. Given this, the preferred way to get the last element is $x[-1], not
$x[$#x] or $x[@x-1], and the preferred way to get the next-to-last is $x[-2], not "$x[$#x-1" or $x[@x-2].
The biggest argument against the non-preferred forms is that their semantics change when the computed index becomes negative. If @x
contains at least two elements, $x[$#x-1] and $x[@x-2] are equivalent to $x[-2]. But if it contains a single element, $x[$#x-1] and
$x[@x-2] are both equivalent to $x[-1]. Simply put, the preferred form is more likely to do what you actually want.
As Conway points out, the preferred forms also perform better, are more readable, and are easier to maintain.
This policy notices all of the simple forms of the above problem, but does not recognize any of these more complex examples:
$some->[$data_structure]->[$#{$some->[$data_structure]} -1];
my $ref = @arr; $ref->[$#arr];
CONFIGURATION
This Policy is not configurable except for the standard options.
