Returns a randomly selected element from an array.
function RandomFrom(const AValues: array of Integer): Integer; overload; function RandomFrom(const AValues: array of Int64): Int64; overload; function RandomFrom(const AValues: array of Double): Double; overload;
int RandomFrom(const array of Integer AValues); Int64 RandomFrom(const array of Int64 AValues); Double RandomFrom(const array of Double AValues);
RandomFrom returns a randomly selected element from the array passed as the AValues argument. In C++, AValues_Size is the index of the last array element (one less than the number of elements.)
To initialize the random number generator, add a single call Randomize or assign a value to the RandSeed variable before making any calls to RandomFrom.
