Strawberry Prolog is specially designed for education. Strawberry Prolog is being developed in the Institute of Mathematics and Informatics and in the Faculty of Mathematics and Informatics.
You can embed ActiveX objects in your Prolog program by the predicate embed_server. Also you can receive events from OLE servers (ActiveX objects). When your Prolog program is OLE server then by the predicate raise_event it can send events to its client program.
You can call external functions from DLL files and from OLE servers. You can call Prolog program as OLE server but for the moment you cannot call it as DLL.
A special tool called Object Browser which gives you the possibility to view the methods and properties of the OLE servers which are installed on your computer (like MS Word, Corel Draw, etc.). This will make easier the task for creating Prolog programs which are using these servers.
You can use ODBC is order to work with databases. The support of ODBC is made through OLE server ADODB.Connection.
You have support of Unicode. Also, you can use different char sets and you can change the char set in the time of program execution by the predicate char_set.
You will find some new and very powerful predicates like print_file. By this predicates and functions you can create really exiting text processing programs. For example the software of Second-Box is made entirely on Strawberry Prolog.
