Okay, thanks, that works!  
 
Another question, though.
Using my current system of selecting a message from the script menu, if a command is selected (eg. /nudge, /block etc.), the script sends just the message.  If any other message is sent, it adds "AutoMessage:" to the start, so it sends in the Plus! auto-message format.
It does this with two variables, "setMsgPlusAM" (the user's way of turning the Plus! auto-message style on or off), and "setnoteMesCmd" (automatically turned on if the message starts with a /), which, if active, disables the "AutoMessage:" start.  The code below will hopefully explain this better.
Javascript code:
function OnEvent_Timer(TimerID)
{
    Debug.Trace("Instant Response  |  Timer completed!");
    if (setMsgPlusAM)  // user's Plus! auto-message setting on
    {
        if (setnoteMesCmd)  // if message starts with a "/" (/command)
        {
            Messenger.OpenChat(TimerID).SendMessage(settingMessage);
            //  do not add the prefix to the message
        }
        else
        {
            Messenger.OpenChat(TimerID).SendMessage("AutoMessage: " + settingMessage);
            //  add the prefix to the message
        }
    }
    else
    {
        Messenger.OpenChat(TimerID).SendMessage(settingMessage);
        //  do not add the prefix to the message
    }
    Debug.Trace("Instant Response  |  Message sent!");
}
Can I set the script so that when the user types "/ir.message /command", the script can turn the "setnoteMesCmd" variable as true, so that the auto-message prefix will not be added?
Is this possible with a wildcard of some sort?  Like:
Javascript code:
if (parameter=="/" + *)
{
setnoteMesCmd = true;
}
else
{
setnoteMesCmd = false;
}
