string vs 'string' parameters

[Ruth Albocher]

hi
can you please tell me what is the difference between the two parameters
in the call:

create_unit(SDunit, 'SDunit_name');   (it is code i need to maintain...
)

(if it helps, then in the create_unit function, i get
    my $self = shift;
    my $type = shift;
    my $name = shift;
    my $unit;
    $unit = $type->new(stuff...);
    $self->{'units'}->{$name} = $unit;   )

isn't both of them strings anyway?

thanks,
ruthie
