Find value within array
Most Sirius $functions have been deprecated in favor of Object Oriented methods. There is no direct OO equivalent for the $Arr_Find function 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 containing 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. |
| value | 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)
