Hi vnpenguin,

Use each_array method in List::MoreUtils module. 

use strict;
use List::MoreUtils qw(each_array);
undef $/;
my $text=<DATA>;

my $a=$1 if $text=~m#v_x \{([^\}]+)\}#;
my @a=split( "\n", $a );

my $b=$1 if $text=~m#v_y \{([^\}]+)\}#;
my @b=split( "\n", $b );

my $c=$1 if $text=~m#v_z \{([^\}]+)\}#;
my @c=split( "\n", $c );

my $ea = each_array(@a, @b, @c);
while ( my ($a, $b, $c) = $ea->() )
{
    print "$a\t$b\t$c\n";
}


__DATA__
v_x {
x1
x2
x3
x4
x5
x6
x7
x8
}
v_y {
y1
y2
y3
y4
y5
}
v_z {
z1
z2
z3
z4
z5
z6
}
