* 
*     THIS PROCEDURE IS THE MAIN MODULE FOR TERMINAL TO APPLICATION 
*     PROCESSING AND IS CALLED INTO EXECUTION WHENEVER THERE IS DATA
*     IN ANY OF ITS INPUT QUEUE .  THE PROCEDURE'S MAIN FUNCTION IS TO
*     ROUTE EACH ENTRY IN ITS INPUT QUEUE TO THE APPROPRIATE ROUTINES.
* 
*     PROC NVFTDQE
* 
*     ENTRY:  
*       TAINPQ  - TERMINAL TO APPLICATION INPUT QUEUE 
*       VCBRDQ  - VCB READ DATA QUEUE 
*       VDATAQ  - VALIDATION DATA QUEUE 
* 
*     EXIT: 
*       ALL DATA IN ALL QUEUES HAVE BEEN PROCESSED. 
* 
*     NOTES:  
*       THE 3 INPUT QUEUES ARE PROCESSED IN THE FOLLOWING ORDER:  
*         1) TAINPQ 
*         2) VCBRDQ 
*         3) VDATAQ 
*       EACH QUEUE IS EMPTIED BEFORE THE NEXT QUEUE IS INTERROGATED.
* 
*     METHOD: 
*       CALL *SSTRQE* TO COPY THE FIRST ENTRY FROM A SPECIFIED QUEUE
*       INTO THE WORKING BUFFER.  EACH ENTRY IS THEN ROUTED TO THE
*       APPROPRIATE ROUTINE TO BE PROCESSED.
