Programming Languages - Grammar

Write your own grammar for a programming language (The set of rules that tell you whether a sentence is correctly structured is called a grammar). You will need to create a context-free grammar for your language. This grammar will need to be able to be recognized via recursive descent parsing. A recognizer is a program which says whether the expressions (sentences) in your source code are syntactically legal. A recursive descent parser is composed of a set of parsing functions, each of which derives from a rule in the grammar. Not all grammars are suitable for recursive descent parsing. Anything that is your own grammar that will work as a programming language is acceptable for an answer to this question as long as it is complete.

An Example using plain English:

sentence : nounPhrase verbPhrase PERIOD

nounPhrase : ARTICLE Adjective NOUN

verbPhrase : VERB nounPhrase

then with further modification the language can use adjectives and finally be:

sentence : nounPhrase verbPhrase PERIOD

nounPhrase : optArticle optAdjList NOUN

verbPhrase : VERB nounPhrase

optArticle : ARTICLE | *empty*

optAdjList : adjList | *empty*

adjList : ADJECTIVE | ADJECTIVE adjLis
