Hi,

I'm new in Perl. I've an assignment to edit perl script.

This is the original line
my $MAILRCP = 'john,anna,steven';

If I have a very long string(additional name to add on) , can I do like this:
my $MAILRCP = 'john,anna,steven,garry,tom,Jeff',
                        'alia','mike','guna','larry';

Please help.
Thanks

You can do it like this:
my $MAILRCP = 'john,anna,steven,garry,tom,Jeff'.
                        'alia'.'mike'.'guna'.'larry';
or like this:
my $MAILRCP = 'john,anna,steven,garry,tom,Jeff
                        alia,mike,guna,larry';
or like
my $MAILRCP = join",",'john,anna,steven,garry,tom,Jeff',
                        'alia','mike','guna','larry';
Depending on what you want the string to contain

to append to the end of a string you use the concatenation operator '.=' but it all depends on the structure of the data you are adding. If the string to add is already formatted exactly how you need it:

$foo = 'this';
$bar = 'that';
$foo .= $bar;
print $foo;


as ozo showed above there are numerous ways to append data to a string.

my $MAILRCP = "john, anna, steven";
#to add a new name to this:
$newnames = "garry, tom, Jeff, alia, mike, guna, larry";
$MAILRCP .= ", ".$newnames;

If this was a subroutine, it would look like this:

sub addNames()
{
my $MAILRCP = "john, anna, steven";
my $newnames = "garry, tom, Jef, alia, mike, guna, larry";
$MAILRCP .= ", ".$newnames
 return $MAILRCP;
}

>If I have a very long string(additional name to add on) , can I do like this:

if you have a number of additional names to add on from some source say from a file its
better to loop and process one record at a time.

putting all the names in one var will take lots of memory.
