Forums Scripts & Popups Help Understanding Access Level Prefixes

I'm trying to understand a script offered to me for the purpose of processing JOIN messages in different ways for different classes of users identified by differing access levels.

A few snippets of code to illustrate:

on ^1!:JOIN:#:{
msg $chan Welcome to the channel, $nick
}
on ^100!:JOIN:#:{
msg $nick Thanks for returning, $nick
}

I can't find a reference to the "^" access level prefix in the mIRC Help file, and while I see nothing in the script that appears likely to have any bad behavior such as file deletion or other obviously bad behavior, I don't like to run any script I don't fully understand. I'm also puzzled by the trailing "!" following the access levels, as that doesn't seem to match the Help file description of a "!" suffix.

Any clarification would be appreciated.

Regarding the ^: /help halting default text (which is not done here)
The exclamation mark here seems to be used as described in /help access levels > "The ! prefix". But as you noted, it would have to precede the number.

So both cases seem to be a case of bad scripting.

Just think of ! prefix as: if ($nick != $me) {

thanks for the clarifications: I'd suspected that the "!" suffix might have been misplaced (or the help text wasn't correct -- the example given in the help file included an "!" as, arugably, part of message text to be displayed by an /echo command. I think I'll suggest a change to the Help file with respect to the "^" prefix so that it is included in the larger discussion of event prefixes, and with an index reference to Halting Default Text.

If you didn't include the level but "!" prefix, I wouldn't call it misplaced. It's used so that the join event won't get triggered by the client that runs the code, with its own join.
