re: I created with the function 'make-instance' my own instances for classes
    I have written. They are named i.e. #<object10000000>. 

Be careful!  these printed out representations are proably NOT names
(i.e., by names, you mean a symbolic "handle" from which you can
subsequently retrieve the object).  As I recall, PCL just prints out
the actual address of the unnamed object; and of course due to the
action of GC, these addresses will change with time.

For saving objects out to files (on "harddisc"?), I would recommend
the CLOS function MAKE-LOAD-FORM (see CLtL2 page 659 and following).
Neither PCL, nor Sun Common Lisp version 4.0, contains this function,
as it was added rather late in the ANSI standardization process. 
[However, experimental versions of Lucid's post-4.0 releases contain it.
Lucid is the supplier of Sun Common Lisp, but I could not at all predict 
when Sun might be making the next release with this functionality in it.]
