Is There a Method That Lets Me Know IF There Is a Next Loop in a While Select Loop? Something like hasNext()?

Hello awesome community! I'm new to AX and its development and I seek your help if you please :)

I have a while select loop, is there a method that lets me know there is a next loop?

Something like if(selectLoop.hasNext())?

because I want to add a "-" in a string with each loop, in each loop i'm adding a new string in a big string variable. But the words appear next to each other without a space or a dash separating them, so I want to know if there is another step in the while select loop to add "-" to the big string between each loop.

Thanks!

    I don't think there is a hasNext when you iterate a table buffer. But I don't think you need that.
    Here's an example:

    boolean firstIteration = true;
MyTable myTable;
str myStr;

while select myTable
{
    if (!firstIteration)
    {
        myStr += "-";
    }
    else
    {
        firstIteration = false;
    }

    myStr += myTable.myField;
}


    The result will be a string with values from myTable.myFieldId, separated by "-".
