function Copy( |

Copy returns a string which is a copy if the Count characters in S, starting at position Index. If Count is larger than the length of the string S, the result is truncated. If Index is larger than the length of the string S, then an empty string is returned. Index is 1-based.
For dynamic arrays, Copy returns a new dynamic array of the same type as the original one, and copies Count elements from the old array, starting at the position in Index.
The Count argument can be omitted. In that case, the string (or dynamic array) is copied from the position Index till the end of the string or array.
