when i'm right, please contact me

On page 19 :

Data sizes and field meaning:
     ar$hrd  16 bits  Hardware type
     ar$pro  16 bits  Protocol type of the protocol fields below
     ar$op   16 bits  Operation code (request, reply, or NAK)
     ar$pln   8 bits  byte length of each protocol address
     ar$rhl   8 bits  requester's HIPPI hardware address length (q) <---- THERE IS A FIELD ar$rhl
     ar$thl   8 bits  target's HIPPI hardware address length (x)
     ar$rpa  32 bits  requester's protocol address
     ar$tpa  32 bits  target's protocol address
     ar$rha  qbytes   requester's HIPPI Hardware address
     ar$tha  xbytes   target's HIPPI Hardware address

On page 20, there is :

Where :
     ar$hrd  - SHALL contain 28. (HIPARP)
     ar$pro  - SHALL contain the IP protocol code 2048 (decimal).
     ar$op   - SHALL contain the operational value (decimal):
               1  for   HARP_REQUESTs
               2  for   HARP_REPLYs
               8  for InHARP_REQUESTs
               9  for InHARP_REPLYs
               10 for   HARP_NAK
     ar$pln  - SHALL contain 4.
     ar$rln  - SHALL contain 10 IF this is a HIPPI-800 HW address <---- THERE SHOULD BE A FIELD ar$rhl TOO, not as$rln...
               ELSE, for HIPPI-6400, it SHALL contain 6.
     ar$thl  - SHALL contain 10 IF this is a HIPPI-800 HW address
               ELSE, for HIPPI-6400, it SHALL contain 6.
     ar$rha  - in requests and NAKs it SHALL contain the requester's
               HW address. In replies it SHALL contain the target
               port's HW address.
     ar$rpa  - in requests and NAKs it SHALL contain the requester's IP
               address if known, otherwise zero.
               In other replies it SHALL contain the target
               port's IP address.
     ar$tha  - in requests and NAKs it SHALL contain the target's
               HW address if known, otherwise zero.
               In other replies it SHALL contain the requester's
               HW addressA.
     ar$tpa  - in requests and NAKs it SHALL contain the
               target's IP address if known, otherwise zero.
               In other replies it SHALL contain the requester's
               IP address.
