$prefix
From Scriptwiki
mIRC supports numeric 005 token PREFIX, and can handle a dynamic set of channel nickname prefixes.
$prefix returns the list of channel nickname prefixes ie. op, halfop, voice, etc. that are supported on a server.
$prefix
- This function has no parameters.
When not connected to a server, mIRC uses a default $prefix value of PREFIX=(ohv)@%+.
Example
$prefix
Returns @+ on QuakeNet as QuakeNet supports only op and voice channel nickname prefixes.
