Interactive Management of Time Series

A very important element in order to study the structure of a national economy, is the organization of a data base consisting of the observations, over time, on the variables which characterize the economy.

The main purpose of this data base is to offer the researcher a supply of information which can be analyzed, revised and updated in a repetitive way. This can be very well accomplished by an interactive approach which, by allowing a direct dialogue between the user and the computer, facilitates this iterative procedure.

A developed interactive user oriented language makes it possible for a large number of users to have simultaneous access to the same information, without interfering with one another and to use this information, in order to study any kind of characteristics of the economy under control.

The central iile holds various series of data which are handled globally by one single program, called IMTS (Interactive Management of Time Series).

By utilizing this program, it is possible to use data both from the central file (official data) and from a private single user file (confidential data).

Summarizing, the research capabilities supplied by the IMTS package are analysis, transformation and regression of stored data. These features can be used independently or in any combination by the IMTS language, which provides a single command for each application: it is, therefore, possible to write regression equations as well as algebraic expressions defining transformations of the economic variables.

In the IMTS environment, not only the IMTS commands but also all the CMS commands are accepted and executed. This is performed by a suitable arrangement of the virtual main storage.

The storage may be divided into four zones:
1) Core of the CMS operating system, free area for system

functions

and the transient area (0-12000 hex.).
2) Low-address free area, designed to hold the work matrix, or to

load the system's or user's module format programs.

(EDIT, COMBINE,

SORT, NEW, CREARCH, APLIUP, etc.) (12000-36000 hex.).
3) Protected area, containing the program routines permanently

held

in the storage (static routines), such as the coding and decoding

routines, I/O routines, etc. (36000-50000 hex. approx.).
4) High-address free area, intended for the dynamic loading of

plotter

or regression routines (50000-end of virtual memory).

Before interpreting a command, the program operates on the NUCON table of the CMS, changing 5 addresses as follows LOWEXT (lower end of the high-
