There is an exception in the standard (page 177, lines 17-21): > If a corresponding list item of the original list item is in the enclosing > device data > environment, the new device data environment uses the corresponding list item > from the > enclosing device data environment. No additional storage is allocated in the > new device > data environment and neither initialization nor assignment is performed, > regardless of > the map-type that is specified. So, the pointer 'a' should inherit map-type ALLOC from the enclosing device data environment. -- Ilya
