+ StringIndexOf ( string, searchValue, fromIndex )

+ 4. Let len be the length of string.
+ 5. If searchValue is the empty string, and fromIndex <= len, return fromIndex.
+ 6. Let searchLen be the length of searchValue.
+ 7. If there exists any integer k such that fromIndex ≤ k ≤ len - searchLen and for all nonnegative integers j less than searchLen, the code unit at index k + j within string is the same as the code unit at index j within searchValue, let pos be the smallest (closest to -∞) such integer. Otherwise, let pos be -1.
+ 8. Return pos.

+ Runtime Semantics: GetSubstitution ( matched, str, position, captures, namedCaptures, replacement )

+ 2. Let matchLength be the number of code units in matched.
+ ...
+ 4. Let stringLength be the number of code units in str.
+ ...
+ 9. Let tailPos be position + matchLength.
+ 10. Let m be the number of elements in captures.
+ 11. Let result be the String value derived from replacement by copying code unit elements from replacement to result while performing replacements as specified in Table 53. These $ replacements are done left-to-right, and, once such a replacement is performed, the new replacement text is not subject to further replacements.
