as a typical task for him/her, have been registered. (v) The system gives for each sequence an attribute to which the user assigns a call name. In the current implementation different areas of the screen for each session are assigned different colours. (vi) At the beginning of the each session the user is requested to choose the working mode, automatic or manual. In the case of automatic mode, the user requests the sequence of queries by call name and from then on, the system performs the appropiate sequence of queries based on data selected for the task. The procedure is a realisation of well known techniques developed in cybernetics and artifical intelligence for self teaching systems. (Wiener 1948, Simons 1984). The experiments have shown that the procedure can be a useful tool for improving the effectiveness and convenience of a user of a GIS user. 4. CONCLUSION. Development of GIS software packages is aimed mostly at satisfying user needs in delivering a final product, of defined form, of information extracted from database. It is achieved through improving the database structure (storage of information) and through the development of tools for extracting information from the database, which should be optimal in the sense of minimum time needed for the extraction of the information. Another approach to improving the characteristics of GIS software should involve endeavours to make it more effective, simple and convenient for the user. Three procedures have been presented for an experimental GIS software to add a measure of intelligence, which will: * recognize an operator, observe his/her habits in making errors and some characteristics of tasks he/she has performed, and then correct the errors, * draw conclusions on appropriate help for tasks performed by an operator, * perform typical tasks by a particular user. The use of the software with these features is more effective and convenient. The ideas which are the basis of the procedures (observing the software environment) can be utilized in numerous applications both in GIS software packages as well as other types of software. For example, it can be used to develop tools for recognizing typical sets of information extracted from the database by each user. This would reduce the time needed for searching for information in the database. 5. REFERENCES. ABEL, D. J., 1989, SIRO-DBMS: a Database Tool-kit for Geographical Information Systems. Int. J.
