Blog - JSE - Putting on the Brakes

23rd July 2021

After a couple of suggestions over at SoCoder, I added Continue and Break/Exit, yesterday.

-=-=-

The Continue command will stop the flow of the current for-loop, jump to the next "Next" command, then carry on looping.
The Exit (or Break) command will do the same, but will exit the current loop instead.
You can additionally add a parameter to Exit, to exit from the number of given loops.

Though this does indeed work, please be aware that it might get really weird if you start adding crazy for/repeat loops inside each other, especially if you throw if/then's into the places where the next/until's are happening.
But I'm sure you're getting used to the language having those sorts of quirks, by now.
