Description

Returns a random integer from a specified range.

RandomRange returns a random integer from the range that extends between AFrom and ATo (non-inclusive). RandomRange can handle negative ranges (where AFrom is greater than ATo).

To initialize the random number generator, add a single call Randomize or assign a value to the RandSeed variable before making any calls to RandomRange.
