- Examples: +
```
 delete each item of scores which is less than or equal to zero

```
 delete each line of file "entries" which is empty
```
```
 delete each item of subscriberList whose expirationDate is earlier than yesterday
```

 set numbers to [1,2,3,4,5,6,7,8]
repeat with each num in numbers by reference
    if num is an odd number then delete num
end repeat
put numbers —> [2,4,6,8]
