CRE_Receive_Open_Close_
CRE_Receive_Open_Close_
CRE_Receive_Open_Close_ provides a logical open or close of $RECEIVE on behalf
of its caller.

The syntax for the native environment is:
variant
defines if the call is an open or a close request. It is nonzero for an open request,
zero for a close request.
attributes
if present and its address value is not equal to zero, points to a structure that
specifies attributes to apply to $RECEIVE. For further information, see Specifying
the Receive File Open Attributes on page 6-32.
cplist
if present and its address value is nonzero in the TNS environment, is a checkpoint
list. In the native CRE environment, this parameter has no meaning and should be
left empty (it is used by COBOL for process pair execution).
