This program was an auxiliary program in the process of excerpting chemical articles for the Gmelin database. This program is my first fully object-oriented program in Visual Prolog 5.



The above picture shows its main menu and the contants of its help file. I have got prefetched 5.25" diskettes and the articles on paper. The diskettes contained one file for each article. My task was the drawing of the structure



and excerpting the data like synthesis paths, infrared spectra from the articles according to complicated rules using a program supplied by Gmelin. The final data files must not contain errors and the individual article files had to be merged but limit of the resulting files was 80 title compound in each one.
