  Is Rain the Answer? [ F. H. D. van Batenburg ]

  In March 1994, Quote Quad published my paper entitled "Powerful and Easy Graphics: A Cry for Help." In that paper I stated that APL needs a universal package for powerful "business" graphics. Such a package should be similar over different computers and over various APL vendors and should offer powerful graphics that are easil activated.

  This paper investigates the product Rain (developed by Adrian Smith), and to what extent it answers that "Cry for Help." A second aim of this paper is to show the readers what Rain can do, and how to do it.
