Copying a User-defined type array

Say I have a user defined type:

Type blah
X as String
Y as String
Z as String
etc....
End Type

Now I create an array of this type say,

Dim foo(0 to 10) as blah

If I have a need to re-sort the contents of the array, can I do something as
simple as:

foo(0) = foo(1) or do I need to physically move each variable in the type
structure from one array element to the other?

Thanks in advance,
Eva

You can do it exactly as written.

BTW, the time to check it would be almost equal to that you spent typing
your request <g>

True true, but it's nice to know that I'm not overlooking something with a
30+ variable type cast :)

Thanks for the confirmation. That saved me a lot of time.

If you're sorting an array of UDTs of such a size it would be very much
faster to sort and / or swap pointers to the UDTs, rather than sorting /
swapping the UDTs themselves. In such cases an index sort would be probably
about twenty times faster than a straight forward sort.
