There's no need to use a SET PATH - CREATEOBJ() resolves the COM server through the registry.

I assume that you have the COM object installed and registered properly already...

>oHPA32N=CREATEOBJECT('Hpa32n.dllClass')
>errormsg=ABC.InitializeDLL()

If you name the object oHPA32N, then you'd say:

errormsg = oHPA32N.InitializeDLL()
