COBOL for Linux on x86 1.1 is the latest addition to the IBM COBOL compiler family, which includes Enterprise COBOL for z/OS and COBOL for AIX. COBOL for Linux on x86 is a productive and powerful development environment for building and modernizing COBOL applications. It includes an optimizing COBOL compiler and a COBOL runtime library. COBOL for Linux on x86 is based on the same advanced optimization technology as Enterprise COBOL for z/OS. It offers both performance and programming capabilities for developing business critical COBOL applications for Linux on x86 systems. COBOL for Linux on x86 is designed to support clients on their journey to the cloud. It enables clients to strategically deploy business-critical applications written in COBOL to a hybrid cloud environment or best-fit platforms, which includes IBM Z (z/OS), IBM Power Systems (AIX), and x86 (Linux) platforms.
As I understand it, there’s still a lot of COBOL code all over the industry, so it makes sense for IBM to make its COBOL technologies available to more people.
