in reply to how can i get the index value of array during runtime

Hi phemal, try using Array::Each module,

use strict; use warnings; use Array::Each; my @x = qw( p e r l ); my $one = Array::Each->new( \@x ); while( my( $x, $i ) = $one->each() ) { printf "%3d: %s\n", $i, $x; }
TIMTOWDI

Otherwise,

use strict; use warnings; my @x = qw( p e r l ); for my $index (0..$#x){ print "$index : $x[$index]\n"; }

Update: Also refer (RFC) Arrays: A Tutorial/Reference

Velusamy R.

[Corion]: (that module has been deprecated by its author already, so that's fair. Although I wonder why the backtracking can't be fixed to handle the formfeeds gracefully)
[choroba]: not enough tuits?
[Corion]: choroba: Yeah, maybe. I'm also unaware of who uses Email:: modules, but that's more my limited horizon of things ;)
[Corion]: Ah - there even is the replacement of Email::Address::XS , by the bug reporter, which hopefully fixes this bug already ;)

    Should cpanminus be part of the standard Perl release?
