Code:
proc/online()
    for(var/M in world)
        usr << "[M]"

var/onlineusrs
    online()

mob/verb/view_more_detailed_log()
    set desc = "View the more detailed log";
    var/HTML = {"
    <html>
    <center>
    <body bgcolor=blue>
    <span style='color:white;'>
    <head><title>Log Files System</title></head>
    <h1><u>more detailed log file</u></h1>
    <br><br>
    <b>Text:</b> [text]<br>
    <b>Online:</b>[onlineusrs] <br>
    </span>
    </center>
    </html>
    "}
    src << browse(HTML,"window=Detailed Log; size=300x600")


Problem description:

It comes up with a onlineusrs : undefined var. I used copied the var name so there shouldn't be any typos.

Thanks in advance.

You cannot set a variable to be a proc. Why you get an "undefined variable" error rather than a major syntax error is puzzling but ultimately irrelevant.

Thanks, but I tried doing that because this doesn't work:

var/onlineusrs
       for(var/M in world)
           usr << "[M]"


It comes up with the following error:

demo.dm:28:error: usr: undefined var
demo.dm:27:error: in: expected 1 argument to 'in'
demo.dm:27:error: for: invalid variable name: reserved word

You can't do that, either.

That's what I said in my last post, because that didn't work, I tried the other one. How would I get this to work?

You cannot use a variable to do what you want. If you want a list of players, generating it from within the proc is going to be easier.

Also note that looping through everything in the world is not going to give you a list of players. Loop through every client (for(var/client/C)) instead.
