| 16. Repeat, for each result in results, |

| m. If functionalReplace is true, then |
| [...] |
| n. Else, |
| i. Let replacement be GetSubstitution(matched, S, position, |
| captures, replaceValue). |

| Code units: |
| 0x0024, N |
| Where 0x0031 ≤ N ≤ 0x0039 |
| |
| Unicode Characters: |
| $n where |
| n is one of 1 2 3 4 5 6 7 8 9 and $n is not followed by a decimal digit |
| |
| Replacement text: |
| The nth element of captures, where n is a single digit in the range 1 to 9. |
| If n≤m and the nth element of captures is undefined, use the empty String |
| instead. If n>m, no replacement is done. |
