<BLOCKQUOTE>
When forming a colon command, the first character, the colon, can be
followed by zero, one or two addresses. These addresses are byte
addresses, in contrast to vi, which uses line addresses.<BR>
The byte addresses can be given in decimal notation or, with a
leading zero, in hexadecimal notation. If you have specified an
address offset (e.g. <B>:set offset=256</B>), this offset has to be
added to the byte addresses.<BR>
Without an address, the whole file is affected or the current cursor
position is used (depending of the command).
