Thanks! That makes perfect sense. So what is happening is the reference address stored in:

    -textvariable => \$fnr{COMPANY_CODE},

[download]

still exists but has been abandoned after

     %fnr = %fnr_new;

No change is detected because what was stored at that address didn't change and will never change (unless the abandoned address got recycled.) Correct?

There are only 10 types of people in this world... those who understand binary, and those who don't.
