	    ===================================================

  The IP library provides IP network communication functions in a similar
way to the Net library.

Routine Summary
===============
  FNIP_Stn()        - format network number
  FNIP_StnFixed()   - format network number
  FNIP_StnNum()     - read dotted network number string
  FNswap_16()       - byte swap 16-bit value
  FNswap_32()       - byte swap 32-bit value

Networking Support Functions
============================
  Various support functions are provided that convert values between human-
readable strings and machine readable values.

Network number display
----------------------
DEFFNIP_Stn(A%)
DEFFNIP_StnFixed(A%)

  IP_StnFixed() and IP_Stn() returns a string containing the dotted network
number. IP_Stn() returns the shortest possible string whereas IP_StnFixed()
always returns the full 16-character string xxx.xxx.xxx.xxx.

Network number input
--------------------
DEFFNIP_StnNum(A$)

  IP_StnNum() converts the dotted network/station string into a network
number.

Byte Swapping
-------------
DEFFNswap_16(A%)
DEFFNswap_32(A%)

  swap_16() swaps the bytes of a 16-bit value, converting &ABCD to &CDAB.
swap_32() swaps the bytes of a 32-bit value, converting &ABCDEF12 to
&12EFCDAB.
