scenario
1. will be met if you double quote the "N" (instead of single quoting). Pls note that line 4 will not be read/printed if script exits on line 3, and your output wouldn't match this.
2. is not met in your second snippet as the condition $3 == "9999" must also be met.
3. doesn't mention you want $3 to be four digits zero padded.
