Hello akki_best, and welcome to the Monastery!

$var1 = $var2; $var2 = $var1;

That won’t work, because by the time you get to the second command, the value of $var1 has already been overwritten by the first command. But in Perl, swapping these values is as simple as:

($var1, $var2) = ($var2, $var1);

P.S. Please format your code using <code> tags. See Markup in the Monastery.

Hope that helps,

[Corion]: Yay. Traditional finance situation averted. Bonds can be quoted in amounts (1_000_000 EUR) or per unit (1 unit). And a traditional error is to trade 2_000_000 piece when you meant to trade 2_000_000 EUR.
[Corion]: (one of my scripts simply catches high amounts and I phone people making that trade, ideally before the payment is due)
[Corion]: The sad thing is that my script sits at the end of the pipeline and can only look at the payments due today or tomorrow basically, while there are many more systems further up in the pipeline
[GotToBTru]: better late than never, I guess
[Corion]: GotToBTru: Sure - there is a long and sad story of many frantic cleanups that led us to implement this notification ;)
