Hi,
Assuming my script use a strict pragma.
If I have a lexical variable declared inside a sub routine and I  
wish to globalize this lexical variable, what are the various  
options to globalise this variable?

Thanks

use strict;
use warnings;

testing();

sub testing {
   my $variable = 2;
   print "I can see you Mr $variable\n";
}

print "So what are the various options to globalise this \$variable  
which is $variable\n";

You don't.  The testing function should return the value and the  
caller should catch it in another lexical variable.  Global variables  
are rarely the right answer to a problem.  What exactly are you trying  
to solve with a global variable?
