Hi, I've inherited a bit of perl code which unfortunatley uses an in-place edit. 

if ($delrec) {

                local $^I = ".keep"; 
                @ARGV = qw(filename);
                while (<>) {
                        do stuff
                }
        }

I'm fully aware of the dangers of using $^I however I'm not able to change that at present for reasons I can't go into. What I would like to do is to flock the file when it is opened. How do I do this when in-place edit is being used in this manner ?
