z390 is great for those of us who use MVS 3.8. It's a more robust assembler than with MVS 3.8. Some differences but nothing you can't work around. I use the MVS380 which has several of the 390 instructions available. It's nice to be able to use relative instructions and some of the newer instructions even though it's MVS 3.8.
