GentleMen,
			

			

			NO VIABLE ALTERNATIVE TO G
			

			NO VIABLE ALTERNATIVE TO E
			

			

			I have been wanting to write DSL when i encounterd ANTLR
			

			althou i have to do my things in C#.
			

			one aspect of this DLR would be like this
			

			

			GET CHART OF COMPANYNAME FROM STARTINGDATE TO ENDINGDATE
			

			WHERE EXCHANGE = EXCAHNGENAME
			

			SCRIPTYPE = EQ
			

			etc etc...
			

			(Example...)
			

			GET CHART OF GeneralMotors FROM 1/1/1990 to 1/1/2001
			

			WHERE EXCHANGE = NewYorkStockExchange
			

			SCRIPTYPE = Eq
			

			

			i wrote the grammar as listed below but cannot get it to work
			

			my questions are as follows according to the
			

			errors i get.
			

			

			Q1) if i have to define a literal which will become a Keyword
			

			should it not be defined as say
			

			

			GET: 'GET'
			

			

			Q2) when i Define My Keywords Then is it necessary to use
			

			them all in my grammar because in testing and building
			

			phase i cannot use all of them i will implement them gradually
			

			as testing one logic to another. i ask this
			

			because i commeted everything in my grammer Except for GET
			

			and it worked. because GET was the only lexer rule i was using in Parser rule
			

			at that time rest of them i had merely created to implement later.
			

			

			Q3) When ANTLR V3 produces Lexer and parser code for C#
			

			in DFA Class the const strings that it produces are all giving error because
			

			it produces like this
			

			

			const string DFA1_eotS =
			

			"1uffff7121uffff11221uffff1374uffff";
			

			

			which becomes an invalid escape sequence assuming that it wanted to produce Hex
			

			i prefix them like this
			

			

			const string DFA1_eotS =
			

			"x01uffffx07x012x01uffffx01x012x021uffffx01x037x04uffff";
			

			

			or should i let them be as they are and merely put @ in front of them like this
			

			const string DFA1_eotS =
			

			@"1uffff7121uffff11221uffff1374uffff";
			

			

			then also error goes away thou..
			

			

			

			//The Code
			

			

			grammar Chart;
			

			

			options
			

			{
			

			language = CSharp3 ;
			

			}
			

			

			tokens

			@parser::header {
			

			// turn of unreachable code warnings
			

			// turn off obsolete code warnings
			

			// turn off unused variable
			

			# pragma warning disable 0162,0618,0219
			

			using System.Text;
			

			}
			

			

			@lexer::header {
			

			// turn of unreachable code warnings
			

			// turn off obsolete code warnings
			

			// turn off unused variable
			

			# pragma warning disable 0162,0618,0219
			

			using System.Text;
			

			}
			

			

			

			

			/*PARSERS*/
			

			// i cannot make even GET to Work....
			

			// NO VIABLE ALTERNATIVE TO G
			

			// NO VIABLE ALTERNATIVE TO E
			

			// is the erroe and then programm is
			

			// lost somwhere looping
			

			// i gues untill it say OutOfMemory .
			

			

			public request : GET  ;
			

			//|SET|COMPARE|SHOW)? EMPTYSPACE+ CHART EMPTYSPACE OF EMPTYSPACE ;//(COMPANYNAME)* ;
			

			

			// i commented the above all to see if i even have the calibre of mking the GET work it did not..
			

			

			/* lEXERS */
			

			

			GET: 'GET' ;
			

			

			SET: 'SET' ;
			

			

			WHERE: 'WHERE' ;
			

			

			EXCHANGE: ('EXCHANGE') ;
			

			

			FROM:'FROM' ;
			

			

			TO: 'TO' ;
			

			

			COMPARE: 'COMPARE' ;
			

			

			SHOW: 'SHOW' ;
			

			

			CHART: 'CHART' ;
			

			

			COMPANY: 'COMPANY' ;
			

			

			CHARTSERIES: 'CHARTSERIES' ;
			

			

			EMPTYSPACE
			

			:  ' ' ;
			

			

			OF : 'OF' ;
			

			

			COMPANYNAME
			

			: ('A'..'Z' | 'a'..'z' | '0'..'9' | '.' | '!' | '@' | '#' | '$' | '%' | '^' | '&' | '*' | '(' | ')' | '+' | '|' | '}' | '{' | ':' | '"' | '?' | '>' | '
			<' ) ;
			

			

			

			WF : ( '
			

			' ) { Skip(); }  ;
			

			

			

			//Code End
			

			

			Lastly could somebody please write a book on ANTLR from the prespective of a c# programmers.
			

			

			just realized this is ajava forum
			

			

			Hey Sirs Java Rules...
			

			

			

			Thanking You
