array data types and performance

Two questions:

1. Is there a way to make an "Array field," where you could refer to
something like afield[1], afield[2], . . . and have them each be an
integer or some other base data type?

2. If not, I think something equivalent could be accomplished using
composite data types written in C++. If there a performance cost to using
routines in shared libraries?
