Here again is the example used in our lecture to show the difference between scoping with blocks and dynamic scoping; fun g x = let val inc = 1; fun f y = y + inc; fun h z = let val inc = 2; in f z end; in h x end; Annotate it as follows: Draw a circle around every block, and number the blocks. Identify each definition of a name. For each definition, describe its scope in terms of your block numbers. For each occurrence of a name (other than a definition of that name), show which definition is used to bind it. Check that this agrees with your scopes.
