I've been trying to figure out what you mean, but I don't think I have a clue.. I looked up execute vbscript on google.com but I just received a bunch of server stuff I think.
Could you elaborate, or would it be best to just use client side variables for this?
Execute also changes the scope of variables, so you'll have to be aware of that (see the doc on it).
Heres two examples in the documentation (multiline, and single line):
Execute "Sub Proc2: Print X: End Sub"
and...
S = "Sub Proc2" & vbCrLf
S = S & " Print X" & vbCrLf
S = S & "End Sub"
Execute S
ExecuteGlobal is used in the same way, it just changes scope. Look up the details.
(the doc is the one you can download on the same page as the script functions, Microsoft Script Host Documentation, it also has the regexp guide and some other things (Including JScript, which makes searching somewhat troublesome at times).)
