I am attempting to edit the standards file used with ArcGIS 10's geocoding engine. Unfortunately, there are 17 files! As far as this website instructs, there should be an .lot file that tells me which locator type uses which .cls files for their lookup. For whatever reason, I can't find any such .lot file OR anything else that tells me what I need to know. Has anyone else cracked this puzzle yet?

My .lot files are located here: C:\Program Files\ArcGIS\Desktop10.0\Locators

The .cls files are here: C:\Program Files\ArcGIS\Desktop10.0\Geocode

A lot file has the code below, which according to your link is supposed to give you an idea which .cls file to use, personally I had luck with the us_addr.cls file.

; ESRI Geocoder Optional Properties

FileMAT                = us_addc4.mat
FileSTN                = us_addrc.stn
IntFileMAT             = us_intsc2.mat
IntFileSTN             = us_intsc.stn

These are the exact places I looked, iteration. Great suggestion, but for whatever reason, the only .lot file in that folder is Composite.lot, which reads as a locator template for Composite Address Locator. – Nathanus Apr 28 '11 at 18:08
