i have a code belows;
my $max_word = 22;
my $advertbody = join (" ", (split (/\s/, $advertbody))[0..$max_word-1]);
print "advertbody limited--> ", $advertbody, "\n";

The code accept up to 22 words.
If there are for example, 10 words comes it prints the rest of 12 words as empty spaces.
It looks like this; abc aksd a                               |as|1233|as| and so on.
This space is wrong, how can i change in code?

You could try putting in an intermediate step where you can reset the max value if you don't have as many elements as the max. For example:

#!perl -w

use strict;

my $max_word = 22;

my $string = "a b c d e f g";

my @temp_results = split /\s+/, $string;

$max_word = #@temp_results unless (#@temp_results > $max_word);

print (join ' ', @temp_results[0..$max_word-1]);

i am sorry.
I can not start with that code.
Could you make it with scalar $advertbody
and print "$advertbody" ?
Is it possible if the words ecceed over 30, then don't accept more than that?
The script becomes datas from another script regularly.

I'm not sure which part of ultimatemike's code you're refering to, but will this do what you what?

use strict;

my $max_word = 7;

my $advertbody = "This code will accept truncate a string of words at position n";

my @advert = split /\s+/, $advertbody;

$advertbody = join ' ', splice(@advert, 0, $max_word);

print $advertbody;

This code will accept truncate a string
