$mask(address,type)
Returns address with a mask specified by type.
Parameters
address - Address to format.
type - Type of format to use.
Available types
0 - *!ident@host10 to 19 uses the same masks as 0 to 9, but instead of using a * wildcard to replace portions of the host, AdiIRC uses ? wildcards to replace the numbers in the address.
Example
; Format 'nick!ident@host' using type '3'. //echo -ag $mask(nick!ident@host,3)
