=head1 Named Variables

The other kind of variables in PIR are named variables.
You declare these with the .local directive, followed by
the type of the variable, followed by the name. The types
of named variables are the same set as the types of
temporary variables, int for integer, num for numbers
(floats), string for strings, and pmc for PMCs (objects).

A simple rule of thumb is to use temporary variables
for variables that are used on 3 or fewer lines of
code, and named variables for any longer-lived variables.
This is just a suggestion, but we think it really helps
improve code readability.

.sub main :main

    .local int answer
    answer = 42     # set local integer var to the integer value 42
    print answer
    print "\n"

    .local num pi
    pi = 3.14159    # set local float var to an approximation of pi
    print pi
    print "\n"

    .local string greeting
    greeting = "Hello"  # set temp string var to "Hello"
    print greeting
    print "\n"

    .local pmc player
    player = new 'String'
    player = "Ford"     # set temp PMC var to "Ford"
    print player
    print "\n"
