# Copyright (C) 2007-2009, Parrot Foundation. =head1 Named Variables The other kind of variables in PIR are named variables. You declare these with the .local directive, with the type of the variable, followed by the name. The types of named variables are the same set as the types of register variables, int for integer, num for numbers (floats), string for strings, and pmc for PMCs (objects). A simple rule of thumb is to use register 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. =cut .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" .end # Local Variables: # mode: pir # fill-column: 100 # End: # vim: expandtab shiftwidth=4 ft=pir:
