It depends. Of course assembler is still used, but doing on what you are doing some system exits can now be written in C/C++.
PL/S (actually I think they are now using PL/X) was was used originally exclusive by IBM. They did market a version of it to the consumer's, but that did not last long. Internally IBM still uses PL/X (or whatever the current version is called) assembler and C/C++.
