thank you, mischief.
considering after I have posted previous mail,
I have come to think that the script below should fail with error and stop execution.
maia% cat foo
#!/bin/rc
./foo
maia%
current rc does not stop execution.
probably not due to protection problem by kernel.
there must be a bug in rc.
