ASP: Possible to access variable defined in a Sub?

[Ken Fine]

I have a Sub which defines a variable. I'm wondering if there's anyway I can
get at that variable outside of the context of the Sub -- to pass the
variable's contents to another page, for instance. Here's some truncated
code:

<%
Sub CreateHTMLPage(getURL,postFile)
Dim TearObj
Set TearObj = CreateObject("SOFTWING.ASPTear")
...
Dim strRetrieval
strRetrieval = TearObj.Retrieve(getPage, Request_GET, "", "", "")
....
....
End Sub

%>

At this point, I'd like to be able to get at the contents of variable
strRetrieval and do something with it. Is there any way to make strRetrieval
"public"?

You could just declare strRetrieval outside of the sub instead of inside.
But it would be better to use a function instead, to return the value.

Function CreateHTMLPage(getURL,postFile)
Dim TearObj
Set TearObj = CreateObject("SOFTWING.ASPTear")
...

CreateHTMLPage = TearObj.Retrieve(getPage, Request_GET, "", "", "")
....
....
End Function

x = CreateHTMLPage val1, val2

What Curt said, plus, when I come across something like this I look at the
structure of my application. Perhaps strRetrieval should be defined in the
caller and passed into your sub. You could also change the sub to a function
and return strRetrieval, or pass strRetrieval ByRef.
