is it possible to make a robot to write an event to a loaded .mrc script file? if yes how do i do it and how do i make the bot test itself? ie:

[MyNick] MyBotnick write On !@*:Join:#:/mode # +v $nick
[MyBotNick] !@*:Join:#:/mode # +v $nick has been written to somescriptfile.mrc

any help will be appreciated thanks.

You can write text to any file using the /write command.

/help /write

This section will show you all the switches and such you would need to do this properly. Probably correlate it with $read or maybe $filter.
