The computational treatment of lexical rules as covariation in lexical entries was implemented in Prolog by the authors in cooperation with Dieter Martini for the ConTroll system ( Gerdemann and King 1994 ; Gotz and Meurers 1997a ) . We tested the covariation approach with a complex grammar implementing an HPSG analysis covering the so-called aux-flip phenomenon , and partial-VP topicalization in the three clause types of German ( Hinrichs , Meurers , and Nakazawa 1994 ) .
