define array size in vbscript as a variable

[avivit]

I tried to use in asp:
Dim x
x=4
Dim myArray(x)

I get error when I use a variable as the array size (OF COURSE I have no problem when setting a number instaed of the variaBle).

Isn't it a possible thing to do?
Thanks

Use
Redim MyArray(x)
to allocate a dynamic array.
Fixed arrays are allocated by
Dim Myarray(number)

It is also "Good Policy" to define the array with Dim first.
Either
Dim MyArray ' Variant to contain array
Or
Dim MyArray() ' Array of Variants
ReDim MyArray(X) ' Actually allocate it.
....
ReDim Preserve MyArray(X+10) ' Resize saving previous
ReDim Preserve MyArray(X-10) ' Resize dropping 10

Arrays are 0 based so if you want 10 items and you are storing in element 0 then allocate with Ybound of 9.
(9) 0 through 9.
Dim X ' Count of items

If X > 0 then
ReDim Myarray(X-1)
End if

I usually start storing in element 1 and leave element 0 empty so I use X rather than X-1.
