Code: on 1:sockopen:sClient: { bset &null 1 0 sockwrite sClient NICK %nick $+ $crlf $+ $bvar(&null,1).text sockwrite sClient USER %nick icq.com irc.icq.com : %nick $+ $crlf $+ $bvar(&null,1).text /* sockwrite sClient NICK %nick $+ $crlf $+ $null sockwrite sClient USER %nick icq.com irc.icq.com : %nick $+ $crlf $+ $null */ } EDIT: Yes it's IrCQ, but on port 7012.

What you're doing, is sending a packet: NICK soupy\r\n and another packet: \0 [null] What I need to do, is send, in a SINGLE PACKET: NICK soupy\r\n\0 Like the topic says, a null terminated string. I could load each character of ' NICK soupy\r\n\0 ' into a binary variable, but how much code would that use? I may as well just write my own client [not really]!

Online Hoopy frood O Joined: Dec 2002 Posts: 1,922	I see what you mean. This is the only way then, bset -t &a 1 NICK %nick $+ $crlf bset &a $calc($bvar(&a,0) + 1) 0 sockwrite sClient &a bset -t &b 1 $+(USER %nick . . :,%nick,$crlf) bset &b $calc($bvar(&b,0) + 1) 0 sockwrite sClient &b It would be nice if we could specify -1 as <N> to append to the end of the variable, but as for now it isn't, so I have to use $calc($bvar(&b,0) + 1) to determine the postion into which the NULL value will be added.

This seems to work [thanks for your help

]:

Code:

 
on 1:sockopen:sClient: {
  %nick = soupy
  ; Set the binary variable &amp;nick to the data that we need to send
  bset -t &amp;nick 1 NICK %nick $+ $crlf
  ; Append a nullchar
  bset &amp;nick $calc($len(NICK %nick $+ $crlf) + 1) 0
  ; Send it off
  sockwrite sClient &amp;nick
  bset -t &amp;user 1 USER %nick icq.com irc.icq.com : %nick $+ $crlf
  bset &amp;user $calc($len(USER %nick icq.com irc.icq.com : %nick $+ $crlf) + 1) 0
  sockwrite sClient &amp;user
  /*
  sockwrite sClient NICK %nick $+ $crlf $+ $null
  sockwrite sClient USER %nick icq.com irc.icq.com : %nick $+ $crlf $+ $null
  */
}

Once again, thankyou for helping.
