Of course? Why?

So you know where the chain ends in a dump.

No. Most compiled languages, including PL/1, don't do forward chaining.
We did it by ourselves for years to make the SYSUDUMPs more readable.
But in the end we gave up and wrote our own dump routine which follows the
back chain starting from reg 13. In the LE manuals it is explicitly
stated
A similar topic:
entry points in SYSUDUMPs Save Area Trace can have a message attached,
containing, for example, function names, compile dates etc.,
if the machine codes at the entry are coded in the right way.
That is, Branch, one byte length field, the message.
