Easytrieve: A Comprehensive Overview of a Mainframe Report Generator

Easytrieve, developed by CA Technologies, is a powerful report generation tool used extensively in mainframe computing environments. With its inception dating back to 1969, Easytrieve has evolved into a cornerstone tool for generating reports and handling data in various large-scale enterprise systems. Over the years, its flexible syntax, compatibility with multiple operating systems, and versatile reporting capabilities have made it a key player in the world of business data management.

What is Easytrieve?

At its core, Easytrieve is a report generation language designed to process data and produce formatted output reports. It is widely utilized in large corporations and enterprises, particularly those that operate in mainframe environments, including systems running z/OS, z/VM, and z/VSE. In addition to mainframe systems, Easytrieve is also compatible with UNIX, Linux, and Microsoft Windows platforms. This broad compatibility has made it a versatile solution for companies that rely on legacy systems while also managing modern computing infrastructures.

The language itself was originally developed to allow users to write simple programs for report generation, making it easier to extract and present data in readable formats. Over time, as user needs and computing environments evolved, so did Easytrieve. Two versions of the language are currently available: Easytrieve Classic and Easytrieve Plus. Both versions serve the primary purpose of generating reports, but Easytrieve Plus introduces additional features that enhance its functionality and ease of use, making it more suitable for modern data processing environments.

History and Evolution of Easytrieve

Easytrieve’s origins trace back to 1969 when it was first developed by a team at CA Technologies. At that time, mainframe computing was the dominant platform for large businesses, and the need for efficient report generation tools was growing. Easytrieve emerged as a solution to automate the tedious and time-consuming process of generating reports manually.

The language quickly gained popularity due to its ease of use, simple syntax, and the ability to integrate with various data sources. In the decades that followed, Easytrieve saw several upgrades, including the introduction of Easytrieve Plus, which brought enhanced features like improved error handling, enhanced data manipulation, and support for more modern computing environments.

Today, while the mainframe market has changed significantly, with many companies transitioning to cloud-based or distributed systems, Easytrieve continues to be used by a number of enterprises that rely on mainframe infrastructure for critical business functions.

Easytrieve Versions: Classic vs. Plus

Easytrieve Classic: This version is the original incarnation of the language. It retains the core features that made Easytrieve popular, including basic report generation capabilities, data manipulation functions, and compatibility with mainframe systems. However, it lacks some of the advanced features found in Easytrieve Plus.
Easytrieve Plus: Easytrieve Plus is an upgraded version that offers enhanced functionality and modernized features. It includes support for additional data sources, improved error handling mechanisms, and enhanced data processing capabilities. This version is more suited for environments that require greater flexibility and performance.

Applications of Easytrieve in Modern Enterprises

Despite the rise of newer technologies and tools for report generation, Easytrieve remains a valuable asset in many large organizations. It is particularly useful in enterprises that operate on legacy systems and require a tool that integrates seamlessly with mainframe-based data storage and processing systems.
