PERFECT...This is EXACTLY what I wanted to do. All I was missing was the SET PROCEDURE TO. (I use PRG classes.)

Thanks, Fernando!

*Approach 1:* Using VCX inside EXE

You just compile an EXE with your classlib and then use externally on other
VFP programs.
Let's say that youur library is called "mytestlib.vcx" and the class you
want to instantiate is called "operations", which have methods for
mathematical operations:

*- In you other VFP Apps:
oOps = NEWOBJECT("operations", "mytestlib.vcx", "test_obj.exe")
? oOps.get_sum(1,2)

*Approach 2:* Using your library not as VCX, but as PRG and doing it the
main program of the EXE

Let's say you have this program as the main program of the "test_obj.pjx"

* main_test_lib.prg
DEFINE CLASS MyClassLib as Custom
    FUNCTION Get_Sum(value1, value2)
        RETURN value1 + value2

Then, when you want to instantiate this class, you can do it this way:

SET PROCEDURE TO test_obj.exe
oOps = CREATEOBJECT("myclasslib")
? oOps.get_sum(1,2)

There are other approaches, but I think that any of these can be useful to
