C++ Builder IDE, Dependancies in LIB files

If you are creating a LIB file and you place a object file in it "A",
however "A" depends on file "B".
Will "B" be automaticially included in the LIB?

No, LIB's are just collections of object files they are not linked.

Also when you have a lib containing object file K and object file L and
you link an executable to this lib which only needs object file K then
the resulting executable won't include object file L (unless K needed L
ofcourse).

Not quite what I was asking, I'll ty to explain better.
I have divided my application up into:
- files that deal with subsystem A into Library A;
- files that deal with subsystem B into Library B; etc
but there is a fair degree of interdependance (ie A units call B units and
vise versa).
Will library A contain object files of B, and B contain object files of A?
(I think they do)
Can I divide my system when there is this interdependance?

No, not unless you put them there.

You might be better advised to put the common functions in one place,
and thus have 3 libraries

No. Each library is its own set of object files.

If you want the linker to look for object files in library B when it is
linking in a particular object file in library A, or look for object files
in library A when it is linking in a particular object file in library B,
you can add this to the source ( or header ) for the particular object file:

#pragma comment(lib,"SomeLibname.lib") // where SomeLibname is the name of
your other library

Sure, why not.
