  2. learn to code or pay someone. Asking for such a trivial thing is a waste of your time as well as ours. It took me under 3 minutes to type it below.

    i want to calculate the sum of an array
    double ArraySum(double Array[], int count=WHOLE_ARRAY, int start=0){
    int size = ArraySize(Array);    if (count == WHOLE_ARRAY)   count   = size;
    int iLimit = start + count;     if (iLimit > size)          iLimit  = size;
    for(double sum=0; start < iLimit; start++)  sum += Array[start];
    return(sum);
}

but i want to know if there are function like arraysize,arraysort .etc system function
