That's a useful function, and documented for me in v6.3. I have long
saved objects to disk for project storage, but "strip" by hand the
pointers I don't wish to save (e.g. ones containing widget trees, etc.).
This is a much cleaner method: simply call HEAP_NOSAVE, ptr, and even if
the save crashes (e.g. out of disk space), your object will be intact.

Thanks,

JD
