Try a:&{ 

           load'jmf'
           createjmf_jmf_ 400;~fn=.jpath'~temp\F.jmf'
           map_jmf_ 'F';fn

           F=:'hello there'

           G=:a:{F
           G=:'goodbye here'

           F
        hello there

Roger will make no guarantees about this behavior or any way to force a
memcopy.
