              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

 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

              INDICATES THE KEY WAS DEFINED AS "COPY".
              TYNOAUCR = APPLIES TO THE CURRENT TRANSACTION AND INDICATES THIS
