=head1 Simple Variables

PIR has two kinds of variables. The most simple kind are
Parrot register variables. Register variables are named with
a dollar sign followed by a single letter and an integer.
The letter corresponds to the type of the variable, I for
integer, N for number (float), S for string, and P for PMC
(any kind of object).

The C<=> symbol can be used to assign a value to one of
these register variables.

    $I0 = 42         # set temp integer var to the integer value 42

    $N3 = 3.14159    # set temp float var to an approximation of pi

    $S5 = "Hello"    # set temp string var to "Hello"

    $P0 = new ['String']
    $P0 = "Ford"     # set temp PMC var to "Ford"

    say $I0

    say $N3

    say $S5

    say $P0
