Find minimum value in array

Note: Many $functions have been deprecated in favor of Object Oriented methods. There is no direct OO equivalent for the $Arr_Min function, because the OO methods emphasize the use of Collections over the use of arrays.

$Arr_Min can be used to find the minimum value in an array. If the minimum value occurs in multiple array elements, $Arr_Min always returns the lowest array element number containing that value.

Syntax

%result = $Arr_Min (array, maxnum)

%result A numeric variable that is set to the array element number that contains the indicated minimum value, or it is set to a -1 if the array or maxnum 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.
maxnum The highest array element number to check. This argument can be used to limit the search to the first n elements in an array, where n is a positive integer.

Examples

In the following example:

%FXARRAY IS FIXED ARRAY(5) %FXARRAY(1) = 81 %FXARRAY(2) = 49 %FXARRAY(3) = 121 %FXARRAY(4) = 25 %NUM = $Arr_Min(%FXARRAY)

%NUM is set to 4.

In the following example:

%STARRAY IS STRING LEN 20 ARRAY(5) %STARRAY(1) = 'HOMER' %STARRAY(2) = 'MARGE' %STARRAY(3) = 'KRUSTY' %STARRAY(4) = 'BART' %STARRAY(5) = 'SELMA' %NUM = $Arr_Min(%STARRAY, 3)

%NUM is set to 1.
