How much demand is there for IBM mainframe Assembler programmers?
Ray Mullin said this: I'll be honest - it's getting smaller and smaller. It's become a niche, mainly for system tools ISVs. Metal C is where the invisible hand of IBM is pushing the industry. Having said that… There is a benefit to learning assembler, or more specifically, the z/Architecture instruction set. You learn how the instructions work, and by reading the 1500+ page Principles of Operation (or, if you don't want that much reading, the General Instructions and Decimal Instructions chapters, plus some of the first 6 others), you can design efficient 3GL programs. In addition, use the LIST option of compilers to see the generated instructions. Through this, you can self-optimize and create efficient code, code that performs, and can save precious CPU and wall clock time. Look at the z390 emulator. This allows you to play with it on your own time on your own machine. You guys know who Ray Mullins is right?
