- You said "record separator" but then you specified the field separator.
- The manpage tells you that RS and FS are just a predefined variables with default values. The setting from the command line as you have it is just an assignment statement that takes place before any user-defined BEGIN section. Therefore, you can change RS, FS and any other variable when processing any action. (It's actually more times than that, but for the novice, it's plenty.)
- FNR will only equal NR in the first file.
