NDF_BEGIN - Begin a new NDF context   

Description:
The routine begins a new NDF context. A subsequent call to NDF_END may then be used to annul all the NDF identifiers (and placeholders) issued since the call to NDF_BEGIN was made.

Invocation:
CALL NDF_BEGIN

Notes:
Matching pairs of calls to NDF_BEGIN and NDF_END may be nested.
