is there a way to make a code that will somehow using /list
or /who or somecrap scan the channels on network and
on given query show all the channels with matching or simmiliar result ?

like this one:

i enter like in code: $$?="Enter query:"
and i type EXPLOIT
then script "scans" channels and finds and SHOWS channels that have in topic word "exploit"

?

You can do this:
Tools/Channels List...
In Match text you enter you word (example: EXPLOIT) and check Match text in topics.

That should work.

mirc 6.03 dont have that crap

thatz why i ask a code

You have it in your toolbar... In every mIRC version newer than 5.51 (not sure for older versions)

click the little globe icon next to the folder icon that has #+ on it

thanx to all
