PL/I extension for project planning and management - may or may not be the same as PLANS, for which little information except a title exists

Abstract: Investment Analysis is a classical application in Long-Range Planning. It deals with the investigation of uncertainties, the evaluation of alternatives, the answer to ?What-if? questions. This paper shortly describes the key problems in this application domain, shows how the flexibility and power of APL can cope with the complexity of the problems, and especially high-ligths how the style of the APL programs and the problem solution influence each other.
Extract: PLANCODE compared to APL From the general characteristics, we can conclude the following: Financial Modeling cannot be automated. It requires the constant interaction with the professional expert during both construction and usage. Therefore, the computer can only support the modeling process - but in a very effective way. The interaction between the professional and the computer must be as quick and direct as possible. Technically, this requires direct access to a time-sharing system via a terminal. Organizationally, the communication problems and time delays involed when going through a formal program development process are prohibitive. In short, the professional, the user himself has to "program". A frightening outlook for most of the users, unless we can provide a "non-computer computer language". These languages can be specialized planning and modeling languages/systems, like the IBM Program Product PLANCODE, or general ones, like APL. Since it would exceed the scope of this conference, we refrain from discussing the mutual merits of either system and immediately go into an example using

Abstract: For the computer-based solution of problems in the area of businessplanning, the planner is supported with user languages, which make it possible to define and initiate computer actions directly and without previous special DP-experience. Based on PLANCODE/I - one of IBM's userlanguages for business-planning - the characteristic features are outlined. Three aspects are considered, namely the adequacy of the language structure of the user's problem solution; the user's facility to create, actualize and display his private data base; and the easy-to-handle operating technique.

Abstract: The purpose of this paper is two-fold. First, to describe some of the different types of computer software which can be used to develop financial models, and to indicate the advantages and disadvantages of each type. Second, to suggest a set of guidelines for relating the financial modeling needs of the user to the attributes of the numerous financial modeling languages which are currently available. The discussion and guidelines are based on Ernst & Ernst's experience in carrying out over 150 consulting engagements which involved the development and use of financial models, as well as Ernst & Ernst's extensive survey and analysis of the some 75 financial modeling languages available from software houses, time sharing vendors, and computer manufacturers.
