Dim a.i(5)

For more details and the background why I want to use it, please see viewtopic.php?t=88114

Same issue probably with lists and maps.

According to the help, it's not a bug:

TypeOf kann verwendet werden, um den Typ einer Variable oder eines Struktur-Feldes herauszufinden.

An array is an array and not a variable. It is not listed as allowed object.

I think at least a(0) can be considered a variable (integer variable in the above example).
So at least

Code: Select all

ShowType(a(0))

should work IMHO.

No, it's an array element.

Look in the help at 'variables' for valid objects.

Of course it's an array element. And what is an array element, generally speaking? A variable.

And even if you don't consider this a bug, it should work!
So feel free to consider this a feature request if you prefer, that doesn't matter.

Yes, it's a feature request and not only for arrays.

Then you can also request the same for lists and maps.

I did mention lists and maps in the first post of this thread.
