 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.
 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.
