in reply to Include Constants from other files

This is because of the way that use constant does its stuff -- it creates subroutines with empty prototypes in the current package. Here's one way to make it work; put the following lines in a file called

package Consts; use constant PI => 3; # We're REALLY approximate, here. "Some true value as the last statement.";

In your main perl file (say, or somesuch) we'd say:

#!/usr/bin/perl -w use strict; use Consts; print "Pi is:", Consts::PI, $\;

See perldoc constant for more information -- there's a section which describes exactly this (search for the word "package")

perl -pe '"I lo*`+$^X$\"$]!$/"=~m%(.*)%s;$_=$1;y^`+*^e v^#$&V"+@( NO CARRIER'
