Quick-and-dirty sample follows:
Hi, nice idea to make it generic on each data-field :-)).

This solution uses a loop too. If possible I would like to avoid looing through the objects. I had something like using indices in mind. With this I would have something like this: myobjects: make hash! [] ; using index,object pairs = [1 obj1 2 obj2] myobjects_names: make hash! [] ; using data-field, index pairs = ["robert" 1 "carl" 2 "joachim" 3] Searching the object with a name joachim would result in object ID 3, than makeing a lookup in the objects and get the object with ID 3. I hope you know what I mean. With this you will have an index for each data-field you want to search for. Remembers me on the good old databases ;-)) Robert
