Syntax
ArrayCopy(<Source array> , <Destination array> [, <Start position of copy> [, <Size of copy>]])
<Source array>: Array
Name of the Array variable to copy.
<Destination array>: Array
Name of the Array variable into which the copy must be performed.
<Start position of copy>: Optional integer
Versions 18 and later
Subscript in the source array from which the copy must be performed. This subscript must be included between 1 and the last array subcript.
This parameter is set to 1 by default. Otherwise, a WLanguage error occurs at run time.
This parameter cannot be used with an associative array.
PHP This parameter is not available.

<Size of copy>: Optional integer
Versions 18 and later
Size of copy.
Caution: The interval of values defined by <Start position of copy> and <Size of copy> must be entirely included in the source array. Otherwise, a WLanguage error occurs at run time.
By default, the copy is performed from the specified subscript to the end of the array.
This parameter cannot be used with an associative array.

Remarks

Copying arrays of different dimensions

  • Simple array: A WLanguage error occurs at run time.
  • Dynamic array: The destination array is entirely re-created (and therefore cleared) with the copy.

Miscellaneous

  • A WLanguage error occurs if the type of the elements found in the destination array differs from the type of the elements found the source array.
  • If the destination array contains elements, these elements are deleted.
  • This function can be used with associative arrays. In this case, it is only possible to copy the entire array. It is not possible to copy part of the associative array.
  • This function cannot be used with the fixed arrays.
