Like the comment in the code says, $1- will contain the the INI filename each time it's called. You won't be able to search for help=1 using $ini() though, to do that you'd use $readini() but you need to specify a section. INI files are in the format:

Code:
[firstsection]
key=value
anotherkey=anothervalue

[anothersection]
somekey=blah


So, what section is the help=1 supposed to be in within the INI file? Or can it be in any section within each file?

Assuming there is a specific section then use this:

Code:
alias checkini {
  ; $1- holds the filename to check
  if ($readini($1-, SECTION HERE, help) == 1) {
    inc %ini_matches_count
  }
}

Just change SECTION NAME to the relevant section name.

If it can appear in any section then you have to cheat and use $read() instead of a proper INI identifier:
Code:
alias checkini {
  ; $1- holds the filename to check
  if ($read($1-, wnt, help=1)) {
    inc %ini_matches_count
  }
}

Spelling mistakes, grammatical errors, and stupid comments are intentional.
