If you've ever seen the MUMPS language (used by many healthcare applications in the federal government), it's not the easiest language to understand. One of my colleagues describes it as looking like "a cat walked across the keyboard". Modules are represented by numbers, so "laboratory" might be 332 and "x-ray" might be 497. That's only the beginning.

A TSRI Approach to Modernized Application Testing

Modernization of code demands a high degree of precision. It is absolutely critical that the reengineered software performs in the same manner as the original. This requires two things: a rigorous approach to code refactoring based upon tried principles which retain the underlying logic; and a well-planned and consistent program of testing to ensure that logic is preserved and improvements do not in any way alter the function of the code. Testing is vital. Companies need to be certain that their modernized critical software will perform according to exact the same rules as the original.

Code Modernization: Focus on COBOL

Enormous amounts of COBOL code have been created and relied upon for decades. It really is the bedrock of early computing. But now, ancient COBOL systems are challenged because the original assumptions under which the code was written are no longer valid. COBOL was designed as a robust business language to handle batch oriented database operations in an ACID environment. Today, these vital systems, including financial, security, transportation, and healthcare solutions continue to run. But access is changed, processing requirements have changed, and the availability of coders to understand, maintain, and augment the systems diminishes year-by-year.

The recent successful and attempted attacks on critical government legacy information systems at the Office of Personal Management and the IRS have provided a stark reminder of just how vulnerable these older systems are. Commercial systems are not immune to criminal and foreign agencies either, and in fact, may have more to lose in the near term in lost revenue, IP theft, negative branding, and the scandals lingering often for years. Sony, Anthem, Banner Health, Home Depot and many others can testify to this fact.

Raytheon has partnered with TSRI on several successful modernization projects. Specifically, several years before the Patriot-Japan project was initiated, Raytheon was tasked with modernizing a set of Patriot Missile Simulation software. Following a formalized decision process, TSRI was selected as the best option for transforming the code from FORTRAN to C++, due to our unique fully automated transformation technology.  So, when Raytheon began modernizing Battalion Simulation Support System and its Preprocessor for the Japanese Patriot Missile system, TSRI was contacted and began work.  

  • Customer: Raytheon
  • Source & Target Language: Fortran to C++
  • Lines of Code: 25,927
  • Duration:  10 months
  • Services: Code Transformation from Multiple Legacy Languages, Automated Refactoring, Installation and Testing Support, Transformation Blueprint®​
