Description

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 dynamical arrays, Copy returns a new dynamical array of the same type as the original one, and copies Count elements from the old array, starting at position Index.
