-- Text - Receives the textual representation of the next lexeme; if any
-- Value - Receives the value associated with the lexeme; if any
--
-- Called to scan the Line and to recognize and remove the next lexeme.
-- Lexeme is set to Lk_Error if we get confused. Lk_Eol is returned if
-- the line is empty or ends with a comment. The Text argument is only
-- set for Lk_Identifier values. The Value argument is changed for any
-- lexeme value that is a name (keywords and parameter names); it's value
-- only has meaning for Lk_Identifiers.
