array size

[firehorse24]

HI,


The array size confused me. I hope someone can help me. I define an array in asp:

dim ary1()
redim preserve ary1(2)

ary1(0) = "A"
ary1(1) = "B"
ary1(2) = "C"

response.write (ary1(0) & "<br>" & ary1(1) & "<br>" & ary1(2) & "<br>" )
response.write ubound(ary1)

I thought array should contain only 2 elements since the size is 2. why the array can have 3 element?

Thanks!

I guess you need to read a little bit more on redmin preserve..

it not only preserves old values but also add any new elements to the array that you specify...

hope this helps..

Thank you very much DNG,

I have another question. I want to save a local array to session. if local array size increased, does the size of the session array automatically increased too? do I just move the local array to session like:

 session("ary1") = localarray1

howcome when I retrieve the array from session I got comma in an element?

Thanks a lot !
