With one extra line of code you get the same functionality w/o using undocumented features.

Additional, that is, to the original name.

Thus we would have:

Options1
Options2
Options3

And the array:

ThisForm.aOptions(1..3)

I assume that closing the form without NULL-ing the array first would cause a dangling reference.

IAC, your alternative might be more flexible, especially for the purposes of Len Speed (removing individual objects).
