Using Genesis, write an action semantics for the simple calculator expression language. You may use either the prefix version of the grammar given in this chapter or the infix version of the grammar presented in previous chapters. Create the semantic functions that map the concrete syntax of the language directly to their actions. Test your creation to be sure it works. Remember, Genesis is a research project and no guarantees are made regarding appropriate error messages. However, it should be pretty stable as it is written in SML.
