There is an older version of GCC that is ported to z/OS on the CBT. As far as I am concerned one of the advantages of GCC is that it is NOT LE so you can use it in places that you cannot use normal z/OS C. And it has a larger library than the METAL option of xlc.

So far, I can be sure only about the size of unpacked source, it is above 600 megabytes. I tried to decrypt abbreviations used above in your message (LE and GOFF), and read those docs: http://www.tachyonsoft.com/s8131db.pdf http://www.tachyonsoft.com/s8139db.pdf In the first one, pp.27 and next, they probably answer your question. In short, gcc for z/Linux produces assembler files that are later munched by gas, Gnu assembler. So, my current understanding of this stuff is that yes, it is possible to create HLASM-compatible file from the gas-compatible one. So I guess, gcc can stop after producing gas files and another program can take it after that point. Guys from Tachyon claim HLASM and gas to be similar. This doesn't solve all the problems, more like good start of bigger effort. Another solution would be allowing ELF on z/OS. This one doesn't seem to solve all problems either.

So my current goal is to learn in a time-sharing fashion, hoping that some time from now I will accumulate enough knowledge to do something interesting (say, with MVS380) during allocated time slot (say, leisure). Unfortunately, I no longer find games interesting enough to make me satisfied with my leisure. So life got more complicated. So far, I can explain with some confidence what HLASM abbreviation stands for (not sure about "M", still working on it).
