INVESTING IN THE FUTURE OF VSEn

 

Our first version of the VSE operating system (OS) enters the market under the name: VSEn V6.3. VSEn is designed to offer non-disruptive compatibility with previous versions of IBM z/VSE (which serves as the basis for VSEn V6.3), leveraging the source code license agreement the company completed on June 1, 2021. VSEn V6.3 also addresses fixes and features that have been applied to IBM z/VSE 6.2 through March 2022, along with the newest releases of the TCP/IP stacks and installation enhancements.
