INTRODUCTION: JavaCup is a parser-generator, and works by creatinga shift-reduce parsing table using the theory and techniques youuse in question 1. In directory on Ouranos:/local/public/cas380/course work20 you will ?nd the speci?cation ofa simple programming language TLM. This comprises of a syntaxscanner and a JavaCup speci?cation with an interpreter in itsaction code. TLM is an extremely simple programming language: ithas 3 integer variable names (x, y and z), simple booleanexpressions, an assignment statement, a do while statement, a printstatement, and a simple user-de?ned function facility. Study thecommented speci?cation and make sure you understand fully how TLMworks. Use JavaCup to create an interpreter for TLM in the usualway. In that directory there is an example program “input program1”that can be run using the JavaCup-created interpreter, asfollows: start; function; do x = x-1; y = x*x; print(x, y); while x > 10 ;end; x = 23; call; x=15; call; finish; TLM is very basic - its parser and interpreter are lacking in datatypes, structured code features etc. TLM only checks the ?rstletter of each keyword. ASSIGNMENT: create your own more advancedinterpreted programming language called MYPL. You must do thisusing the already written TLM as a base. In other words startingfrom the components of TLM, build up your own language and interpreter. Your language must have the following enhancements.(*i*) Long variable names: rather than only x, y or z, your languageshould allow a range of variable names to be used. (*ii*)Declarations: your language must only allow variable names to beused if they have been previously declared (*iii*) Keywords:keywords such as while end etc should be parsed only if they arespelled properly (*iv*) Function: The function declarationstructure in TLM is extremely basic: e. g. only one function can bedeclared, it has no name, and it must be declared at the beginningof the program; and the function has no parameters or localvariables.
