Stored procedures
Copies the content of a WLanguage array or associative array to another one.
Remark: This function can only be used on WLanguage arrays.
Example
MyArray is array of 2 strings
MyArray[1] = "WINDEV"
MyArray[2] = "WEBDEV"
MyArrayCopy is array of 2 strings
MyArray.Copy(MyArrayCopy)
arrA1 is array of int
arrA1 = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
// Copy the first 3 elements from arrA1 to arrA2
arrA2 is array of int
arrA1.Copy(arrA2, 1, 3) // [1, 2, 3]
// Copy 4 integers from position 4
arrA3 is array of int
arrA1.Copy(arrA3, 4, 4) // [4, 5, 6, 7]
// Copy the end of array from position 6
arrA4 is array of int
arrA1.Copy(arrA4, 6) // [7, 8, 9, 10]
Syntax
<Source array>.Copy(<Destination array> [, <Start position of copy> [, <Copy size>]])
<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
Index in the source array where the copy must start. This index must be between 1 and the last index of the array.
This parameter is set to 1 by default. Otherwise, a WLanguage error occurs at runtime.
This parameter cannot be used with an associative array.
AndroidAndroid Widget JavaPHP This parameter is not available.
<Copy size>: Optional integer
Copy size.
Caution: The interval of values defined by <Start position of copy> and <Copy size> must be entirely included in the source array. Otherwise, a WLanguage error occurs at runtime.
By default, elements are copied from the specified index to the end of the array.
This parameter cannot be used with an associative array.
AndroidAndroid Widget JavaPHP This parameter is not available.
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.
