I don't think I've swapped variables since writing bubble sorts 40 years

I do occasionally.
On report parameter forms where I have a date range, if the
dates are in the wrong order, I simply swap the dates rather than
giving an error message.
I have another program where the table can be viewed in forward
or reverse order. I have a swap in there.
I also occasionally use call-by-reference. Again, not often,
but when you need it, it is good to have.
