With two numbers in X and Y, X≤Y? X<>Y checks if X is the smaller of the two. If it is, both are swapped. So this sequence always returns the larger number in X and the smaller one in Y. Likewise, X>Y? X<>Y returns the smaller number in X and the larger one in Y. Now assume there are three different numbers in X, Y and Z. X>Y? X<>Y will put the larger one in Y and the smaller one in X. Roll down the stack one level to compare this larger number with the third one. X≤Y? X<>Y will put the largest of all three in X. So the program simply is: Code: 01 LBL A Or on the 12C and others without an X>Y? test: Code: 01 X≤Y? You can easily extend this example. This is what we get: Return the largest of two numbers: Code: 01 LBL A Return the largest of three numbers: Code: 01 LBL A Return the largest of four number: Code: 01 LBL A Dieter

Thanks Dieter
Didn't think about that before now your version is very interesting. Gamo
