    Probably you mean " many *elements* there are" :)

    Well, if it's a one-dimensional array, it's easy. From Delphi's help: "The standard function Length returns the number of elements in the array’s first dimension."

    Example: somewhere you defined aNames:
    var aNames: array[1..50] of string;

    Now, you can find the number of elements like this:
    NumberOfElements := Length(aNames);
