join or concatenating a string	Can't Post

I would like to join a specific string with numbers:
My data:
LC 4
..... LC 23120
...LC 53347
etc. My data is more complex than that with other words before and after the list above.
So I wrote:
#!/usr/bin/perl
$string = join( "", "LC ", "4" );
Print "Joined String is $string\n";
and the result is:
Joined String is LC 4
Instead of Joined String is LC4

How can I remove the white space between LC and numbers so it would look like this: LC53347 ?

Thank you. [:/]

Something like this:

my ($field1, $field2) = split " ", $start_string;

my $end_string = "$field1$field2\n"

You have a space after the LC in:

Code

$string = join( "", "LC ", "4" );

That's why you end up with "LC 4" instead of "LC4".
