Unloading and Reloading a Referenced Object

When you unload a loaded referenced object, it frees the memory but does not delete the reference.

Unload – If you have a reference object named NS, you can set its IsLoaded attribute to False to unload all the referenced items as follows:
```
lFileReference = FBFindObjectByFullName( "FileReference::NS" )
lFileReference.IsLoaded = False
```

Reload – You can reload the reference object by setting its IsLoaded attribute to True as follows:

lFileReference = FBFindObjectByFullName( "FileReference::NS" )
lFileReference.IsLoaded = True
