ubound

UBound(array name[,the largest dimension of the array])

UBound 讀取指訂的陣列中最大的註標

UBound(arrayX)
returns the largest dimension size

UBound 陣列的極大( Up Bound)
LBound 陣列的極小(Low Bound)

Example 1-----------
<%
arrayX=Array("link","ezer","com")

for I=0 to UBound(arrayX)
  if I<UBound(arrayX) then
     response.write arrayX(I)&"."
  else
     response.write arrayX(I)
  end if
next
%>

Example 2 -------------------
<%
dim dayArray(99)
dayArray(0)="8/5/2006"
dayArray(1)="9/5/2006"
dayArray(2)="10/5/2006"
dayArray(3)="11/5/2006"
dayArray(4)="12/5/2006"
'-----------Use document.write( )-------------------------
document.write(UBound(dayArray))
document.write("<br>")
document.write(LBound(dayArray))
'-----------Use response.write -----------------------
response.write UBound(dayArray)&"<br>"&LBound(dayArray)
%>

當 array 未被設限大小時, UBound array 
值將跟著 array 值的增加而變更

Example 1 result:
link.ezer.com
Example 2 result:
99
0

------- attention ----------
Example1 has no dim arrayX=(2)
so the UBound(arrayX) can be different when array change

Example2 has dim dayArray(99) already
so the array max =99
