NDF_END - End the current NDF context

Description:

The routine ends the current NDF context, causing all NDF identifiers and placeholders created within that context (i.e. since a matching call to NDF_BEGIN) to be annulled. Any mapped values associated with these identifiers are unmapped, and any temporary NDFs which no longer have identifiers associated with them are deleted.

Invocation:

CALL NDF_END( STATUS )

Arguments:

STATUS = INTEGER (Given and Returned)

The global status.

Notes:

• Matching pairs of calls to NDF_BEGIN and NDF_END may be nested. An error will be reported if NDF_END is called without a corresponding call to NDF_BEGIN.

• This routine attempts to execute even if STATUS is set on entry, although no further error report will be made if it subsequently fails under these circumstances.
