<%

Dim arr()

Now you want to insert a record

ReDim arr(0)

arr(0)="raja"

Now you know there is one more record
ReDim arr(1)

' this will create two elements.

' but the value in arr(0) will be lost

ReDim Preserve arr(1)

' this will create two elements.

' the value in arr(0) will be preserved

arr(1)="roja"
