ParserDefs: DEFINITIONS =

	BEGIN

	--	Definitions for the Parser phase of the CIF 2.0 Parser.  InitParser should be called once before ParseStatement is used.  ParseStatement scans a valid CIF command and returns a code indicating what type of command was scanned.  ParseStatement makes calls on routines in the Interpreter to handle the semantics of each statement.

	CommandType: TYPE = {Wire, DefineStart, DefineEnd, DeleteDef, CallSymbol,
		Layer, Flash, Polygon, Box, End, Comment, NullCommand, 
		SyntaxError, SemanticError, UserCommand};

	InitParser: PROCEDURE RETURNS [BOOLEAN];
	FinishParser: PROCEDURE RETURNS [BOOLEAN];


	ParseStatement: PROCEDURE RETURNS [CommandType];

	END.
