If the picture handle was read from resource, which function should be
called?
For example,

pictH& = FN GETPICTURE(128) 'or FN GETRESOURCE(_"PICT",128)
' do someting with pictH&
' and then we have to release it because it is not purgeable.
CALL RELEASERESOURCE(pictH&) ' <- Is this right?

This works for me.

TIA.
