| Description |
The RandomRange function generates a random Integer number within the range RangeFrom to RangeTo inclusively. *
This provides a more convenient version of the System unit Random function.
Both use a pseudo random number sequence of 232 values. Each time you run your program, the values generated will be the same, unless you reposition the generator to a different part of the sequence using the Randomize or RandSeed functions.

for i := 1 to 5 do
ShowMessage('Random number : '+IntToStr(RandomRange(652, 656)));
end;
