Millions of COBOL legacy systems today manage the majority of the world’s business and financial applications. These programs are the backbone and heartbeat of the worldwide daily business applications and transactions. Other languages have been converted to COBOL to achieve the reliability, efficiency and maintainability that COBOL programs have supplied for 50 years.

Since 1975, our clients have been using our DCD III product. Our President and Founder, Marshal Crawford designed the highly successful tool to help the programmer with the daily maintenance of COBOL programs on the IBM mainframe. For 37 years, DCD III has helped programmers achieve in minutes what used to take hours of research on the mainframe. With 80% of the expense budget going to maintenance, we have been able to provide substantial savings with our cost savings software.
