We have discussed elements of this topic over and over again here, chiefly in terms of its difficulties for novices. As Bob Shannon has already noted, it is not at all a new once; but it has to be new to every programmer at some time.
When you have a question, look first in the archives of this and the assembler list. (If you pose a question here or there that has been discussed at length recently, you will inevitably get short shrift.) The assembler list is likely to be a better forum for detailed technique questions. They are legitimate here too, but more of the people who can answer them authoritatively hang out there. Let me also offer you the perhaps gratuitous advice to test at least your early code in a sandbox LPAR. It is easy to get PC code very wrong in a way that can compromise an LPAR for use by anyone else, requiring an IPL for recovery.
