OK - so __FILE__ is the name of my script, but I will admit to not understanding what you're trying to do with it.

When I run your version of the BEGIN code, I get 

Use of uninitialized value in string eq at /apps/bin/blah/reconcile_wi
+thdotsh.pl line 68.
        main::BEGIN() called at /apps/bin/blah/reconcile_withdotsh.pl 
+line 73
        eval {...} called at /apps/bin/blah/reconcile_withdotsh.pl lin
+e 73

where lines 68 and 73 are: 
67 BEGIN {
68    unless( $ENV{ +__FILE__ } eq __FILE__ ){
69        delete $ENV{LIBPATH};     
70        $ENV{ +__FILE__ } = __FILE__;
71        exec $^X, __FILE__, @ARGV; # relaunch without LIBPATH
72    }
73}

It isn't __FILE__ that is the uninitialized value (as I put a print command in), so presumably its the "$ENV{ +__FILE__ }" but I can't manage to print that to check - and being in a BEGIN statement I can't step through it in debug.

Also, in both versions the script just ends (as opposed to terminating with an error).

Maybe I should be a heretic and go back to using COBOL on a mainframe! Do any still exist?

Cheers
