which will never do anything since "frameName" is a string variable with a
discret value and therefore not vois at all.
I believe that what you are looking for is a way to detect if there is a
marker in your score labeled like some certain expression.
There is an archaic element in lingo called labelList which really is not a
list at all but rather a string with all the labels of a score separated by
RETURN.
so something like this might work for you:
on isDefinedLabel expression
return (the labellist contains expression & RETURN)
end
