If you mean a regular OSCLI call : well, yeah. Why
would you think OSCLI is an exception among the OS
calls ?

Its handler on the 2p side is a trifle more involved
than others though. If an error is generated by the
command line execution, like all other errors it is
sent back via an entirely seperate path (which then
generates a BRK type error). And the handler receives
an 'execute' indicator if an executable has been pumped
across (it then enters the executable tentatively,
restoring the previous CAO pointer and HIMEM if it
returns).
