$Arr Find

Find value within array

Note: 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)
