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;
}

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