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

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.
