how about 'eval'?

Your loop would become: 

        print;
        s/(?<=\S)\s/ \$register,/;
        $register= eval $_;
        print "currently: $register\n";
        print "------\n";

Yes, I have to admit that it's a bit ugly because of the RE.
Update: Thanks to rediablo for showing me that "eval" is unwanted.
