I have a my variables set up to be prz1, prz2, prz3.
Then  I want to loop through a for and display all the text out on new lines.
for i = 1 to 30
	response.write(prz1) 
next

Open in new window


how do i change the variable to be prz & i, since this simple syntax doesn't work?

First, use an array instead of individual variables:

Dim PRZ(1 To 20) As Variant
PRZ(1) = 1
PRZ(2) = 23
...

Then concatenation is easy:

Response.Write Join(PRZ, vbCRLF)

If you want all the variable values on one line separated by commas and spaces:

Response.Write Join(PRZ, ", ")

If I understand you correctly you want to be able to reference your variables as przi where the i is the loop value

This you can't do - you would have to store your variables in an array as suggested by zorvek.

In other scripting languages it is possible to create references to variables dynamically but as far as I am aware ASP does not support this.

strPrizes="prz1, prz2, prz3"
arrPrizes=split(strPrizes,",")

For each prize in arrPrizes
    response.write prize &"<br>"
next

response.write "<ul>"
For each prize2 in arrPrizes
        response.write "<li>"&prize2&"</li>
next
response.write "</ul>

If you needed to get the array dynamically you can use a dictionary.

Dim dPrize,counter
counter=0
Set dPrize=Server.CreateObject("Scripting.Dictionary")

strPrizes="prz1, prz2, prz3"
arrPrizes=split(strPrizes,",")

For each prize in arrPrizes
    counter=counter+1
    dPrize.Add counter,prize
next

response.write dPrize.Item(2) ' should be prz2
