OPS5, originally designed by Paul S. Troutman (PhD ’60), is an imperative programming language, widely noted for being the first such language ever to be developed for a commercial expert system, and the first computer language to use an operator precedence/disregard system. OPS5 is a set of rules-based programming language, commonly called an object-oriented programming language, that can be used by a computer engineer to develop and debug real-world systems. The programming language has had an enormous influence on the fields of software development, information systems, programming languages, database design and programming methodology.

It is a language that compiles to C++ and is based on the theory of dependent types (a form of static typing) and inheritance. While it was originally intended for small applications, today, many programmers are creating complex programs with several levels of inheritance, dynamic and static typing, and multiple inheritance and specialization.

There are many reasons for choosing an operational systems programming language over a scripting language, or any other type of programming language. It can be faster and simpler than other scripting languages because it is built upon rules and algorithms. It has fewer bugs than scripting languages and thus allows programmers to concentrate on more important aspects of the programming project. It also gives the programmer the ability to add new modules without affecting any code written.

The main advantage of usingOPS5 as opposed to scripting languages is that it is highly customizable. This means that the programmer can change the syntax and behavior of the system without having to rewrite every part of the code. For instance, if the programmer wants the system to log a message whenever a certain condition occurs, he could change the condition in order to implement the desired message.

The other advantage of using the OPS5 for an operational system is that it is easy to use. One can write one line of code to perform complex tasks like logging all messages sent and received by the system and can then simply insert that into the system to get a detailed report for each event. Since the language is designed with object-oriented programming principles, it makes the task of maintaining the system very easy to do. and the programmer can easily add new modules if required. without affecting the existing code.

The only drawback to using the OPS5 for an operational system is that it is limited in its functionality. For instance, one cannot make a program to print the XML reports on a UNIX server as there are not enough capabilities of the language for this task. If one wants to store files on a remote server, then he can choose to use FTP and send the file through FTP or network. but when it comes to a file that needs to be sent to a remote server like an ASP, then the programmer needs to know the exact URL and encoding for that specific file to send it correctly. Also, if one wants to create a user-defined function in the system like an SQL command, then the programmer must know what he is doing and not rely on the default “SQL_CALC_ON” functions.

These drawbacks aside, OPS5 programming is considered to be an excellent choice for many different applications. One can use it for web programming, application programming, database design and integration, data mining, and a number of other applications. It is also a great tool to have at a corporate or business environment for controlling large systems. If used properly, OPS5 can make one’s life much easier and simplify the task of running the system.

There are many sites online that provide a thorough tutorial on how to useOPS5 for programming. They are very simple to follow, and a basic knowledge on the subject should be all that is needed to understand them. One can also learn a lot about the language by joining the Yahoo! Developer Network for more information on the subject.
