Copy

Returns a substring of a string or a segment of a dynamic array.

Structure

Copy(S; Index, Count: Integer): string;

Copy(S; Index, Count: Integer): array;

Parameters

Return Value

Description

S is an expression of a string or dynamic-array type. Index and Count are integer-type expressions. Copy returns a substring or sub array containing Count characters or elements starting at S[Index].

If Index is larger than the length of S, Copy returns an empty string or array.

If Count specifies more characters or array elements than are available, only the characters or elements from S[Index] to the end of S are returned.

Note

When S is a dynamic array, Copy can only be used as a parameter in a call to a procedure or function that expects an array parameter. That is, it acts like the Slice function when working with dynamic arrays. |
