     NAME       : TTYFLG
     DESCRIPTION: HCPTYI AND HCPTYO PARAMETERS
     DSECT      : TTYFLG
     FUNCTION   : PARAMETER LIST CREATED WHEN HCPTYI IS CALLED.
                  PARAMETER LIST CREATED WHEN HCPTYO IS CALLED.
     LOCATED BY : PARAMETER LIST IS SPECIFIED BY HCPTYI AND
                  HCPTYO.
     CREATED BY : PARAMETER LIST IS CREATED BY HCPTYI AND
                  HCPTYO.
     DELETED BY : PARAMETER LIST IS DELETED BY HCPTYI AND
                  HCPTYO.
     RELOCATION CONSIDERATIONS : None
     DEFINED BY -  HCPTYI AND HCPTYO AS TTYFLAGS:
                  TYNOLNFD = APPLIES TO THE CURRENT TRANSACTION AND INDICATES
                  80 CHARACTERS OF DATA WERE FOUND DURING THE 3101
                  COMPRESS. IF PROMPT=TTY NO LINE FEED IS NEEDED
                  TO END THE WRITE TRANSACTION SINCE THE DEVICE
                  DEVICE WILL PROVIDE IT.
                  TYPFERR = THE PFKEY WAS DEFINED AS "TAB" OR "COPY" AND A MESSAGE
                  MUST BE SENT TO THE TERMINAL TO NOTIFY THE USER.
                  TYPFDLAY = THE PFKEY WAS DEFINED AS "DELAYED" OR "RETRIEVE" AND
                  THE DEFINITION MUST BE WRITTEN BACK TO
                  THE TERMINAL USER.
                  TYPFTABK = WORKS IN CONJUNCTION WITH THE TYPFERR FLAG. WHEN ON,
                  THIS FLAG INDICATES THE PFKEY WAS DEFINED AS "TAB", OFF
                  INDICATES THE KEY WAS DEFINED AS "COPY".
                  TYNOAUCR = APPLIES TO THE CURRENT TRANSACTION AND INDICATES THIS
                  WRITE WAS QCNNOCR AND THE USER WANTS THE CARRIER TO
                  RETURN AT THE CURRENT POSITION.
                  NO CARRIER CONTROL SHOULD END THE WRITE.
                  TYNEEDLF= APPLIES TO THE CURRENT TRANSACTION AND INDICATES THIS
                  READ OR WRITE ENDED IN A CR. A LINE FEED MAY BE REQUIRED
                  TO PLACE THE USER ON A CLEAN LINE.
                  WHEN TRANSACTIONS TO/FROM THE TERMINAL END WITH CR, ASSUME
                  THE USER WANTS THE DEVICE TO BE IN LINE-BY-LINE MODE.
