Interesting. Does this display a specific element of the array
TestArray on your computer? Would you mind creating an array and
storing Now() to each element? Then tell me the specific value of,
say, the 803rd and 804th elements. I'd also like to see you change the
value of, say, the 755th thru 799th elements to 123. If you can print
actual output from your script and paste it with the code that would
most useful.
Thanks.
