Hi All,
This is the type of thing where threads tend to go south here:
Whoever wrote the documentation didn't understand how Arrays in
RunRev work.
That would be hard to believe. Jeanne DeVoto, who wrote most of the
documentation, is one of the foremost documentation experts on

No problem. Errors happen.
Second, that a mistake is made in any product's documentation does not
necessarily mean the author doesn't understand the

It seems pretty clear that the delete command will remove an array
element with the key you specify. That's how associative arrays work.
The Documentation says:
delete global myArray[17] -- removes 17th element of that array
of the elements in the array.

Hi,
Please see text from the RunRev 2.8.x Dictionary copied below. Is the

Correct? Does it remove the 17th element, rather the element with the

Thanks a lot

It deletes the key that is named 17. Try the following to check:

repeat with k = 1 to 20
put abc into tArray[k * 2 + 1]

I agree with the versatility of associative arrays, but the conventional
array uses different functions, like in Flash, so the following may help a
new user who has experience in other programming languages.

Hi all,
Back to Rev after being side-tracked for over a month, and glad to be
coding in it again.
I've looked through the docs, but I can't find a way to delete an entire
array. I'm already cringing at how easy I expect it to be, but I have to
ask.
Thanks,
Steve Ralston
