If-Then-Else Needed Please Help

[grant9]

I need an if-then-else to add either A or B to C. I need to add the largest of A and B and put the result in total. I have tried with something like below but it doesnt work.

A > B ->
Total is A + C;
Total is B + C,

Any guidance will be appreciated.

Cheers

How about:
[tt]
max(A,A,B):- A >= B.
max(B,A,B):- B >= A.
addmax(Total,And,Or1,Or2):-
max(M,Or1,Or2),
Total is And + M.
[/tt]
Then:
[tt] addmax(T,123,456,789).[/tt]
will give:
[tt]T = 912[/tt]

 

[grant9]

That works perfect.

Thanks a lot TonyGroves.
