Kednos has closed its doors!
After many years supplying PL/I compilers to OpenVMS and Tru64 UNIX users around the world, from October 2016, Kednos will cease trading. The PL/I compilers, run-time libraries and integration tools will no longer be supported or sold by Kednos.
However, this website will remain as a place to download software kits for those still holding valid licenses. It also is still possible to request a hobbyist license and use the compilers in a non-commercial capacity.
What is PL/I?
PL/I is a powerful high-level programming language that is a superior alternative to using Fortran for scientific applications, COBOL for commercial applications and C for systems programming. Enjoy using the King of Programming Languages and don't worry about buffer overrun exploits.
