In DGD, the program of an object is the "control block", in which there
is a "program" field for the byte code and line number information.
The control block is constructed in src/comp/control.c.  Recompiling an
object completely replaces its control block; this is done in
src/comp/compile.c::c_compile().

The control block and the "dataspace" of an object are declared in
src/data.h, and are managed by src/data.c (high level) and src/sdata.c
(low level).

(I have to cut this short, if you have further questions I will try to
answer them later.)
