*      NRCSSTP               L.T.NGUYEN     84/08/21
* 
*    2.FUNCTIONAL DESCRIPTION:  
*      MAKE SSTP CALL AND PROCESS REASON CODE RETURNED FROM O.S.
* 
*    3.METHOD USED: 
*      SETU UP SSTP PARAMETER BLOCK.
*      CALL OSREQ TO VALIDATE SSTP CALL.
*      PROCESS REASON CODE RETURNED:  
*      - IF NON-ZERO REASON CODE: 
*          IF REASON IS SWAPED OUT LINK THIS PWL TO ACB PWL RING. 
*          ELSE SET UP TO ABORT APPLICATION LATER.
* 
*    4.INPUT PARAMS:  
*      ACBADD - ADDRESS OF ACB OF APPLICATION TO RECIEVE FILE.
*      PWLADD - WORKLIST FROM PIP.
*      FTNORD - ORDINAL FNT OF FILE TO BE SWITCHED. 
*      REASON - REASON CODE RETURN TO CALLER IF ERROR ENCOUTERED. 
* 
*    5.ROUTINES USED: 
*      OMSG :                - SEND DAYFILE MESSAGE.
*      OSCHAPP:              - SCHEDULE THIE APPLICATION. 
*      OSREQ:                - CALL OPERATING SYSTEM TO PROCESS SSTP.
