You mean, When I type /? or ? I get "What?" in purple ?
If yes, then do you mean /? or just ?, If you mean /? then

pawn Код:

if(!strcmp(cmdtext, "/?")) 
     {
        SendClientMessage(playerid, 0xFF00FFFF, "What?");
        return 1;
     }

and for just "?"

pawn Код:

public OnPlayerText(playerid, text[])
{
    if(text[0] == "?")
    {
        SendClientMessage(playerid, 0xFF00FFFF, "What?");
        return 0;
    }
    return 1
}
