Probably you mean "...how 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);
