[pml] how to updating my pml in pdms?

I have a .pmlfrm (in pmllib), and I modify it.
My question is that do I have to exit module  and get in again to make changing updated to PDMS?
Or is there any command that can doing the updating thing?

after you save the .pmlfrm

just kill  and show again to see the update for example

kill !!pmlForm
show !!pmlForm

There is a special command: pml reload form !!pmlForm

Thank you!!
