int dict dict                         create dictionary with capacity for
                                      int elements

dict length int                       number of key-value pairs in dirt

dict maxlength int                    capacity of dict

dict begin -                          push dict on dict stack

- end -                               pop dict stack

key value def -                       associate key and value in current dict

key load value                        search dict stack for key and return
                                      associated value

key value store -                     replace topmost definition of key

dict key get any                      get value associated with key in dict

dict key value put -                  associate key with value in dict

dict key known bool                   test whether key is in dict

key where (dict true) or (false)      find  dict in which key is defined

dict1 dict2 copy dict2                copy contents of dict1 to dict2

dict proc forall -                    execute proc for each dict element

- countdictstack int                  count elements on dict stack
