(isType typeName obj) If the argument is of the specified type, true is returned. Otherwise,it false is returned.
Here are a number of links to Lambda coding examples which contain this instruction in various use cases.

Here are the links to the data types of the function arguments. Here are also a number of links to functions having arguments with any of these data types.
