Thanks to both you and Burkhard for replying.
One of the problems turned out with the field types, in that
I had mistyped DOUBLE as DUOBLE, and the rest was solved
following a suggestion from Russell Kackley across the hall from
me, to de-reference the other end of the assignment.

Have you checked all field types and array sizes? The record allocates memory for the fields. If the record and the C-code disagree on the types you might write to wrong memory locations. The C-code should always check the types (at least in the init routine).

Hi all,

I have a rather funny (funky) problem with a genSub record.
It outputs several values, one definitely a string, some
integers and some floats. After trying to get the integer
(long) values out yesterday (got the first one out, but not
the rest) and resorting to strings (it's channel access,
after all) I tried to add some floating point (double)
values to that today. Again, I got the first one out,
but not the rest, and lost the last character of the
last string. Converting all to strings didn't help
this time. However, I got the last character of the
string in VALF back by putting it into VALJ (after
the doubles).
This is a rather complex mechanical system (for those
who know a bit about our instruments: the mechanisms
in the CGS4 cryostat) where things have to be calculated
depending on one another, and so I'd prefer to keep
all of this together.
There are a few things I can try yet, but if anybody
can tell me an easy solution I'd very much appreciate it.

Thanks in advance,
Maren
