Re^2: -textvariable won't update when using hash element

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.

"So what is happening is ..." Yep, got it in one. I'm sure I've been bitten by this in the dim distant past, and spent considerable time trying to figure out where the bug in Tk was! True laziness is hard work	[reply]
