Here is one way to do it with splice and join: `use strict; use warnings; my $string = "PERLPERLPEBLPEBLPERL"; my @array = split( '', $string ); while( scalar @array ) { my $extracted = join( '', splice( @array, 0, 4 ) ); print "[$extracted]\n"; }` [download]	[reply] [d/l]

Here is one way to do it with splice and join:

use strict;
use warnings;

my $string = "PERLPERLPEBLPEBLPERL";

my @array = split( '', $string );

while( scalar @array )
{
    my $extracted = join( '', splice( @array, 0, 4 ) );

    print "[$extracted]\n";
}
