|
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).
