This is an easy way to token for a group secluded by whitespaces.
Example:
StrToken("Hello, this is a test.",3,out,24);
out will end up being "is".

public OnPluginStart()
{
    new String:test[]="Hello, this is a test string.";
    new String:out[]="";
    StrToken(test,5,out,192);
    PrintToServer("%s",out);
}

stock StrToken(const String:inputstr[],tokennum,String:outputstr[],maxlen)
{
    new String:buf[maxlen+1];
    new cur_idx;
    new idx;
    new curind;
    idx=StrBreak(inputstr,buf,maxlen);
    if(tokennum==1)
    {
        strcopy(outputstr,maxlen,buf);
        return;
    }
    curind=1;
    while (idx!=-1)
    {
        cur_idx+=idx;
        idx=StrBreak(inputstr[cur_idx],buf,maxlen);
        curind++;
        if(tokennum==curind)
        {
            strcopy(outputstr,maxlen,buf);
            break;
        }
    }
}

I have used functions that deal with strings toknes in mIrc script and they are vary useful. Try add more function that will deal with tokens like:
a function to remove a token from a string (remove N token found matching something..), a function that will count how many tokens in a string, replace a token in a string, find the postion of a tokken in a string, check if a token is in a string, function that adds a token to a string and token shotring function.
