The trick I usually use is (under CMS VM/SP) :

 #CP D 688        (This is the address of  ACMSRET in NUCON)
 #CP B xxxxxx   where xxxxxx is the result of the preceeding command.

I'm sure this is not very good, because some memory is not returned to
the system, so I load a dummy module by :

 LOAD TOTO (CLEAR NOMAP

(The system respond by : "The following names are undefined : TOTO")
and this seems to clean up the memory pointers.
