If the problem you are facing is similar in nature, you
might be able to work around it by having a variable of
the same type as the array elements, assign to it the
record that you want to modify, make the modification
in the single record variable and then assign that
single record variable back into the array element that
it came from.

i.e. something like:

declare
a rectype[];
r rectype;
i integer;
begin
...
r := a[i];
r.field := newvalue;
a[i] := r;
...

It actually works the way you suggested. Not nice, but as long as it works, it's ok ;-)

I didn't even realise that you could have an array of records.
I've only ever used arrays of scalar values.

Yes, if that wasn't possible, I would have had to switch to a series of Array of scalar values.
