* 
*     EXIT    1. IF NETON SUCCEEDED, AN APPROPRIATE DAYFILE MESSAGE HAS 
*                BEEN ISSUED AND PARALLEL MODE HAS BEEN SET.  ALSO, A 
*                CALL TO NETFUNC HAS BEEN MADE WITH CODE 1, INDICATING
*                THAT NVF IS TO BE SWAPPED OUT WHEN IT ISSUES A NETWAIT 
*                IF THERE IS NO DELIVERABLE DATA ON A NETGETL OR NETGTFL
*                CALL.
*             2. IF NETON FAILED, THERE IS NO RETURN.  NVF TERMINATES 
*                NORMALLY AFTER ISSUEING AN APPROPRIATE DAYFILE MESSAGE.
