My assembler coding skills are quite basic, and I understand what the instructions do, but I cannot understand them by reading the PooP. Reading that book is another completely different thing. Something I've not been able to do very well on my own.
We dinosaurs were a bit lucky, as IBM not only provided decent documentation, but also the source. That made it a bit easier to discover how to use, and not to use, some of the instructions (my infamous example being the source for IEFSD095, the job separator, which introduced me to BXH R5,R5, but also served as a warning, as the author failed to take advantage of character oriented instructions to manipulate character data). It also helps when you employer accepts a certain proportion of "non-productive", i.e. educational use. And I consider www.cbttape.org an invaluable source for brushing up on skills.
