| 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, N |
| Where 0x0030 ≤ N ≤ 0x0039 |
| |
| Unicode Characters: |
| $nn where |
| n is one of 0 1 2 3 4 5 6 7 8 9 |
| |
| Replacement text: |
| The nnth element of captures, where nn is a two-digit decimal number in the |
| range 01 to 99. If nn≤m and the nnth element of captures is undefined, use |
| the empty String instead. If nn is 00 or nn>m, no replacement is done. |
