TCB is a 16-bit unsigned offset from the address in TCBTIO. If
the DD name is blank, you need to scan through the TIOT entries
(ignore voided entries) until the last non-blank entry prior to
your offset. The JFCB address (minus 16 bytes) is obtained from
the TIOT entry in TIOEJFCB after that's

Thanks, Eileen, for showing me the way. I have been able to create a C

Because you can't append to a member. You can update in place, but I

I have since found out that there is a lot more that members don't support. So
what I have now resolved to do is whenever I need to append, or seek, or any
of the other unsupported things,
It seems the symptoms have led me to draw wrong conclusions. The fact that
