of course! love it!

Ahhhhhh, i didn't know that! Well in that case it works!
looks alot tidier now then:

ClassMethod ExecuteClassMethods(Functions As %DynamicArray) As %Status
{
    s arrFns = Functions.%GetIterator()

    while arrFns.%GetNext(.Key, .Obj) {

        s arrArgs = Obj.Arguments.%GetIterator()

        while arrArgs.%GetNext(.aKey, .Item) {
            s Args = aKey + 1
            s Args(Args) = Item
        }

        d $ClassMethod(Obj.Class, Obj.Method, Args...)
    }

    q $$$OK
}

Well when i try that in the above code as:

ClassMethod WriteSegment(Functions As %DynamicArray) As %Status
{
    s arrFns = Functions.%GetIterator()

    while arrFns.%GetNext(.Key, .Obj) {
        s arrArgs = Obj.Arguments.%GetIterator()

        while arrArgs.%GetNext(.aKey, .Item) {
            s Args(aKey + 1)=Item
        }
        d $ClassMethod(Obj.Class, Obj.Method, Args...)

    q $$$OK
}

i get an error in the called function:
<UNDEFINED>zWriteSomething+1^Report.Elements.1 *Arg1
the Args array looks like this:
Args(1)="Hi"
