Good follow up to the questions.
Item #3 was a little surprise to me. In fact, what it returns as the length
is the number of elements defined (regardless of whether they contain any
data). I created an array that had data in elements 1,2,4,6 & 9 (elements
3,5,7 & 8 were empty) and it retuned a length of 9. I then did a resize on
the array making 13 the minimum size and it returned a length of 13 (which
is where I think the question started).
As the presentation pointed out - you learn something every day. I was
certainly under the impression that if I created 13 elements but only
populated 9 elements it would return 9 as the length. I stand corrected
from my statement last night.
Would be interested in seeing an example of using and array in a server
variable. Can not imagin a practical example of this one. Also was not
aware of the change in CF 5.0 on creating a structure.

Subject: Questions from last night's meeting.
Chris Elmore offered these answers to some questions that were raised at
last night's presentation about structures and arrays.
>Here are the answers for the questions last night:
>
> * Arrays in server scope? Yes
> * listToArray - will it wipe out the existing array or overwrite only
> the needed/used cells? Wipeout
> * ArrayLen for an array with cells [1] and [9] defined? 9
> * ListToArray - can it have multiple delimiters? Yes
> * ArrayResize(array, size) - does it initialize the cells? NO.
> * ArrayResize(array, size) - does it initialize skipped (undefined see
> #3) cells? No
> * will isArray(array, size greater than 3) work? No, the number must
> be b/w 1 and 3.
> * is structNew() required to define a structure? Yes. CF 5.0 does not
> dynamically set stSomeStruct.somekey to be "stSomeStruct" as a structure
> with somekey as a key. Some structures are defined by default (cookie,
> form,cgi, etc.)
> * Does structKeyExists evaluate the same as isDefined on structures?
Yes
