empropCx;p] :The function remprop searches the list, x, looking for a11occurrences of the property p. When such a property is found,its name and the succeeding element are removed from the list.The two "ends" of the list are tied together as indicated bythe dashed line below,I &nameof the propertyThe value of remprop is NIL.where,where prog2[u;v] has the value v, and uses u to effect an action.- se t [x; y 1 : machine language- setq[x;y] : machine language; special formThe - set and setq functions are used to change the valuesof the program variables when using the program feature (seeSection 4.5). The program variables are initially bound tonull lists.Note that (in S-expression form),
