LotusScript code to test presence of a person in a group

I have been asked to perform a task  to test if the user logged in is a member of a certain group to edit data in one form and was told it could be done in Lotusscript. Could anyone give me a idea about how to start with this, it would be much apprecated. Thanks :)

In that case: have you considered list that group in an authors field? Or rather: link the group to a userrole and list the role in an authors field. You'll have to apply that field/value to your documents, but from that point Domino will automatically control you can (not) edit the documents. Any other way is not a security measurement!

In answer to your question: QueryOpen and QueryModeChange (set 'Continue') would be your friends. In addition you could use the @IsMember formula in a hide formula of the edit button.

Why is that not a security measurement? One could still use smarticons, agents etc. to change field values on the document.
You could start in the group document and recursively look into it's content (in each group you could find people and groups).
Easier, but kind of "dirty" is to use evaluate on @UserNamesList.
It's not dirty but a great way to get this info.  

dim v as Variant
const certainGroup = "certainGroup"

v = Evaluate({@IsMember("} & certainGroup & {";@UserNamesList)}
If Isnumeric(v) Then
    If v = 1 Then Print "User is a member of the required group"
End  If

Thanks for your comments :) This is going to be used to lock down the form so only "certainGroup" can edit it. I can see that the first bit of code is to test to see if the user is in the group but how would you code the bit for if the user isnt in the group. would a prompt work? and where would this piece of code be best put? Postopen?
Thanks again for your help.

For author fields to work, please remember to limit user access to 'Author' in the ACL, an only a few select individual with higher access.  Also, remember to assign the role to your servers....
