=head1 DESCRIPTION

A tutorial lesson about Parrot's string operations (continued).

=head1 STRING OPERATIONS

To find the length of a string in PIR, use the length opcode. It works on
any variable containing a basic Parrot string, but not the String PMC.
C<length> returns an integer value, and 0 means an empty string.

=cut


.sub main :main

    $S0 = "Hello"
    $I0 = length $S0
    say $I0

    .local string text
    text = "longer string"
    $I1 = length text
    say $I1

.end
