COBOL

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 But now, ancient COBOL systems are challenged because the original assumptions under which the code was written are no longer valid.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.

COBOL & C++ - Premera Blue Cross

Premera Blue Cross required the assessment, transformation and re-factoring of its existing Automated Document Assembly System (ADAS). ADAS was written in WANG COBOL and self generated WANG COBOL programs tailoring health care booklets for specific customer needs. TSRI was selected to assess, transform, and re-factor the WANG COBOL code, migrating the system into a C++ Windows NT environment with full functional equivalency.

  • Customer:  Premera Blue Cross
  • Source & Target Language: COBOL to C++
  • Lines of Code: Nearly 50,000
  • Duration: 4 Months
  • Services: Code Transformation, Automated Refactoring, Testing and Implementation Support, Transformation Blueprint®

The Reliability & Maintainability Information System (REMIS) is a key component of the Air Force Depot Maintenance System. Ten years after the successful modernization of REMIS in 2004, the US Air Force reached back out to TSRI to modernize the rest of the system as well as take the C++ we already produced to Java. The project was delivered on time and under budget by almost half a million dollars.

COBOL Refactoring - State of Oregon / OPERS

The Oregon's Public Employees Retirement System (OPERS) serves approximately 300,000 employee members, inactive members and retirees from more than 850 public employers. OPERS required a major maintenance action of the OPERS Benefit Estimation Subsystem (BESS) and Benefit Calculation Subsystem (BCSS) to address changes in Oregon State retirement regulations. TSRI's automated refactoring capability was used to consolidate the applications and remove dead and redundant code.
