Changes Introduced in V1.11

The following describes the most significant changes which occurred in the NDF_ system between versions V1.10 and V1.11:

1. Limited support for NDF array components stored in ``delta' compressed form has been introduced. The new routine NDF_ZDELT will create a delta compressed copy of an input NDF, and the new routine NDF_GTDLT will return details of the compression of a delta compressed NDF. See §.

2. A new function NDF_ZSCAL has been added, which creates a SCALED copy of an input NDF with SIMPLE or PRIMITIVE array components.

3. A new function NDF_CREPL has been added, which allows an NDF placeholder to be created via a specified environment parameter.
