MaSomme is numeric
MaSomme = MonTableau.Sum() // MaSomme = 6

<Result> = <Array>.Sum()

<Result>: Numeric

Sum of the numeric elements found in the array.

<Array>: Array variable

Name of the one-dimensional array of numeric types containing the elements whose sum must be calculated.

<Result> = <Array>.Sum(<Member>)

<Result>: Numeric

Sum of the values of members.

<Array>: Array variable

Name of the one-dimensional array of structured types. Permitted structured types are: class, dynamic class, structure, dynamic structure.
Note: In an array of dynamic classes or dynamic structures, if the element is not allocated, it is ignored.

<Member>: Character string
