Apply a mathematical operation to every value in a (text) list.

Sample Input:
ListOperation ( "1 2 3 4" ; "+" )
Sample Output:
10


 Then copy & paste into FileMaker Advanced's Edit Custom Function window.

Description:

Substitutes the supplied mathematical operator for spaces and hard returns -- modifiable for other substitutions, of course -- and evaluates the resulting formula. Great for adding or multiplying a list of numbers.

Note: does not error check for leading/trailing spaces or returns -- use my "TrimCharacter" function to handle such cases.

Note: these functions are not guaranteed or supported by BrianDunning.com. Please contact the individual developer with any questions or problems.
