* 
*     ENTRY    HOP COMMAND IN *WCBUF[1]*, *HDRCMD[1]*, AND *PARMS[0]* 
*              WITH *WCBUF* DEFINED IN TEXTSS, AND *HDRCMD* AND *PARMS* 
*              DEFINED IN TXCMDNV.
* 
*     EXIT     A SH/ISD SM IS SENT TO OUTGOING-TRAFFIC-QUEUE *OTQ*, 
*              AND A NULL TERMINAL-TEXT LINE IS SENT TO CONNECTION- 
*              TRAFFIC-QUEUE *CTQ*. 
* 
*     METHOD   USE THIS HOP COMMAND-S VERB IN THE PARAMETER LIST TO 
*              DETERMINE IF A FORCE SHUT-DOWN OF THE HOST IS REQUIRED.
*              BUILD SH/ISD SM WITH FORCE-SHUT-DOWN FLAG SET/NOT-SET, 
*              AND SEND IT TO *OTQ*.  BUILD A NULL TERMINAL-TEXT LINE 
*              WITH INPUT-ALLOW-FLAG SET AND SEND IT TO *CTQ*.
