You could use getRelationship() as I sent earlier, but it would be a bit
clumsy. Easier to test for validity directly, something like (off the
top of my head ...)
function canItBeValid p1, p2, pRelationship
put sample(p1) into p1
put sample(p2) into p2
switch pRelationship
case "="
if p1 is among the lines of gOlder[p2] then return false
if p2 is among the lines of gOlder[p1] then return false
return true
case "<"
if p1 = p2 then return false
if p1 is among the lines of gOlder[p2] then return false
return true
case ">
if p1 = p2 then return false
if p2 is among the lines of gOlder[p1] then return false
return true
default
ask "bad relationship" && pRelationship
return false
end switch
end canItBeValid
but I see from a later email you have something already working, so go
with that :-)

Hi Alex,
well what I need to do is to check if the relationship I am wanting to set is
valid or not, before I write it to the database. I might not be clear enough.
But my goal is not really to check for existing relations, but the validity of
the data I am about to enter into the Database. So if there is no relation at
all, any relation is valid. Direct relations are clear and indirect relations
need to be checked for.
Maybe I just dot understand how I would use your script in that case.
Sorry for the confusion.
Malte
