The main difference between anonymous methods and nested functions is that one can return a reference to an anonymous method from a function, the anonymous method can access local variables from that function and even after exiting the function, the variables are still valid. This means that local variables accessed in a anonymous method end up on the heap. However, I fail to see reasonable use cases for anonymous methods _______________________________________________ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-pascal
