$regsub performs a regular expression match and then substitute/replace, returns the number of match found and store the result in a %var or &binvar, more information about regex in mIRC here
- name - The optional name of the regex, to be used later to retrieve captured group with $regml or $regmlex
- input - The input text
- regex - The regular expression for PCRE
- subtext - The text to use to replace the match, this parameter is evaluated once prior the regex call, you can use backreferences \1 \2 etc, but it doesn't support the markers of $regsubex such as \t \n \A etc. , you cannot use $regml or $regmlex inside the subtext parameter since it's evaluated prior the regex call.
