Re: #defines ? or Constant Data in perl ?

2002-10-04 Thread Andie Kirkpatrick 

What I tend to do, though its only partly satisfactory, is to use a reference to a 
constant.

my $PI=\3.141592654;
print PI is $$PI\n;
$$PI=4; # Modification of a read-only value attempted at...

# Problem is you can assign the reference to something else
$PI=\4; # Works just fine only the laws of physics break down

 Subject: #defines ? or Constant Data in perl ?


  Greetings,
 
  Is there some such way to define a constant, or #define style
  variable in perl ?
 
  I  typically have the need to define data which is just to
  eliminate the need for magic numbers etc.
 
  thus far i have just defined variables such as :
 
  my $WELCOME_MSG = Hello!;
  print $WELCOME_MSG;
 
 
  Which does work, but is not really what i want...
 
  Any ideas anyone ?
 
  Thanks,
  Lenny
