If variable exist then do something.. else do nothing?.

[gus121]

Hi i have a function which i am including on multiple ASP pages via an include file and is been called on multiple pages.

However i wish to run a little bit of logic if a particular variable exists. however i dont want to have to go through and declare the varible on all my pages or remove the option explicit i have setup on my pages.

Is there a way to say if var exists then run code block?

Thanks

Angus

may be you could do this in the global.asa file

something like this:

Sub Session_OnStart
    ...
    Session("myvariable") = True
    ...
End Sub

and on all your pages you could do:

if Session("myvariable")=true then
'do this 
else
'do that
end if

Hi thanks for your input.

I decided to declare the variable on each page instead using a include file which is attached on all pages.

Thanks for your time.

Kind regards
