Fellow Monks,

Is there a way to determine on a windows platform if a perl script is invoked by double-clicking on the file, through the "File association" ?

My issue is that when I run from a DOS prompt and my script provides logging to STDOUT, the logging is visible after the script ends. When I double-click, the perl script starts in its own DOS box, outputs its logging to STDOUT, finishes, and the DOS box vanishes. I end up having to put: 

print "Hit <Enter> to continue\n"; 
my $y = <STDIN>;

at the end of all my scripts. I want that code to be conditional on being invoked from a double-click file association.

thanks for you help,

Update:

I was having trouble with the ouse.pm solution. It's good for double-clicking. However, if I invoke a script from the command line as: 
> foo.pl

instead of 
> perl foo.pl

I get the wait condition in the first case because the file association is still being used.

I updated ouse.pm to use the Win32::Process::Info module to see if the parent process is Windows Explorer. UPdate 2: forgot a line 
=head1 NAME

ouse.pm

=head1 SYNOPSIS

    perl -Mouse file.pl

=head1 DESCRIPTION

Install in your perl/lib or perl/site/lib directory
in a file named "ouse.pm".  Then enter the following
commands:

   assoc .pl=Perl
   ftype Perl=C:\Progra~1\perl\bin\perl -Mouse "%1" %*

Then clicking on a *.pl file will cause the script to
run in a new window but the window will (usually)
not close when the script finishes.

   ReadMode(0);
  }
  else
  {
   print "Press ENTER to close: ";
   <STDIN>;
  }
 }
