INPUT stack lift: 32S vs. 42S

[Dave Britten]

It occurred to me that the 42S behavior actually provides a feature that the 32S doesn't: the ability to press R.Down to cancel your change and revert to the original value. And if there are no menus open, you can see the old value in the Y register after you've started typing. If it's best to code defensively and never trust the stack layout after an INPUT on either model, then the 42S version is overall more flexible.
