Find value within array
Note: Many $functions have been deprecated in favor of Object Oriented methods. There is no direct OO equivalent for $Arr_Find, because the OO methods emphasize the use of Collections over the use of arrays.
$Arr_Find can be used to find an array element with a specific value.
Syntax
%result = $Arr_Find (array, value, minNum)
| %result | A numeric variable that is set to the array element number that contains the indicated value, or it is set to a -1 if the value was not found or if the array or minNum is invalid. |
|---|---|
| array | An array of string, float, or fixed values. This array must be a single dimensional array and must not be an array in an image. |
| value | The value to be located in the array. If this value is found in multiple array elements, $Arr_Find always returns the first (lowest element number) array element containing this value. |
| minNum | The lowest array element number to check. This argument can be used to skip the first n array elements, where n is a positive integer. |
Examples
In the following example, %num is set to 3:
%fxarray is fixed array(5) %fxarray(1) = 2 %fxarray(2) = 3 %fxarray(3) = 5 %fxarray(4) = 8 %num= $Arr_Find(%fxarray,5)
In the following example, %num is set to 5:
%starray is string len 20 array(6) %starray(1) = 'ONE' %starray(2) = 'TWO' %starray(3) = 'THREE' %starray(4) = 'FOUR' %starray(5) = 'ONE' %starray(6) = 'TWO' %num = $Arr_Find(%starray, 'ONE', 2)
