I don't think so (I'll double check c.a to be sure), but, DOS gives
DOSBase in a register to every process on startup (along with other
things like the command line) and I am pretty sure Lattice/SAS startup
just uses this.  Obviously SysBase is fetched from AbsExecBase.

True, but my main point is from the point of view of main() of a
normal program you never have to worry about SysBase and DOSBase yourself.
