This function is basically the same as the addProp function for property lists, but it deletes all properties with the name of the property you want to add. This makes sure your lists stay small and prevents errors because lists will no longer have duplicate entries. Usage is simple: addAProp(listName, propertyName, value) listName is a propery list, propertyName can be either a string or a property, value can be anything. If no value has been specified, the property will be deleted. No value is NOT the same as "" (an empty string) or 0 (zero). I hope you find this usefull, good luck coding!

-- before adding a property to a list, delete all properties with the same name on addAProp me, a, p, v   if ilk(p) = #string then s = symbol(p)   repeat while a.deleteProp(s)       end repeat   if ilk(v) <> #void then a.addProp(s, v)     return a   end
