I think I've seen similar uses of GPR 0 in CMS code. (CDC 6K series made B0 a hardwired 0, so developers weren't so tempted. But it still caused pipeline block.) >3.Any other cool stuff available from __gtab()? > No help in <https://www.ibm.com/docs/en/zos/2.5.0?topic=files-gfunch-gtca-gtab-functions>.
