OK, I'll buy that. Then let's take a different approach, and make it clearer that it's Humpty Dumpty's version of "add", so maybe neither I nor Alice will get hung up on it: OLD The "add" operation adds a new value at the target location. The operation object MUST contain a "value" member that specifies the value to be added. NEW The "add" operation performs the following function, depending upon what the target location references (see details below): o If the target location specifies an array index, a new value is inserted into the array at the specified index. o If the target location specifies an object member that does not already exist, a new member is added to the object. o If the target location specifies an object member that does exist, that member's value is replaced. END That may be wordier than we need, but I think it makes the point... feel free to wordsmith. With something like that, I think we can say that we had to pick a name, "add" was picked, and it means exactly what we choose it to mean - neither more nor less. And that's glory for you. Barry
