I know dimOf only can be used with primitive values, so what can I use to get the length of a string array to make this dynamic?

for (i = 0; i <= dimOf(ClockNums); i++) {

switch (_Activity) {

case 'Add': Valid ="ADD"; break;

case 'Delete': Valid ="DELETE"; break;

case 'Update': Valid ="UPDATE"; break; }

}

Hi KeithM,

Can you please elaborate? What is it exactly what you want to achieve? Can you provide some background on the process?

Hi KeithM，

Yes.

The dimOf function is intended for X++ arrays that are declared as the following X++ primitive types: Boolean, date, int, int64, real, utcDateTime.

You can use Array to replace your dynamic array ,and then use lastIndex() to get length of array.

It's hard to guess what you want, because your description is vague and your code doesn't make sense.

Note that string is a primitive type in X++.

If you want "a dynamic array", maybe you shouldn't use an array at all. There are other collection classes available, such as List and Set.
