Again I am wondering why are trying to do something by shelling out to a Perl program from an ASP when you could simply do:

if nm <> "" then
   MsgBox("Test",0,"test")
end if
[download]

In your ASP. Anyway where are you expecting the Perl generated Message Box to display? - you are running the perl program in the server context which effectively does not have a GUI, the message box will not be displayed for the client.
