| This is a sample template about USERNAMEs. | |
| The $(USERNAME) is my favorite user. | |
| I especially like $(USERNAME+2) if it is fresh. | |
| I especially like $(USERNAME-2) needs additional 0. | |
| I especially like $(USERNAME*2) if it is fresh. | |
| I especially like $(USERNAME/2) if it is fresh. | |
| I especially like $(USERNAME+92) needs one leading zeros less than original. | |
| I especially like $(USERNAME+10092) overflow. | |
| The $(USERNAME) is my favorite user again. | |
| His $(USERID) seems okay to me. | |
| My favorite spice is $(SPICE). |
