   ... > Feat:"Number=Sing"                // adds a feature "Number=Sing"  (Number: deletes the feature)

   ... > Lemma:this(Misc_Translit)         // set lemma to the key Translit from the Misc comlmn
   ... > Lemma:this(Form)+"er"             // set lemma to Form + "er"
   ... > Lemma:"de" + token(Form)          // set lemma to "de" +  Form
   ... > Feat:"Featname"+this(Lemma)       // set the feature Featnamer to the value of Lemma
   ... > Feat:"Gender"+this(Misc_Special)  // set the feature Gender to the value of the Misc Special
   ... > Misc:"Keyname"+head(head(Upos))   // set the key "Keyname" of column MISC to the Upos of the head of the head
   ... > Lemma:substring(this(Form), 1, 3) // set lemma to the substring (1 - 3) of Form
   ... > Lemma:substring(this(Form), 1)    // set lemma to the substring (1 - end) of Form
