Quick look in the console:

sa: mod[3] |number: 12> |number: 0> sa: mod[3] |8> |2> sa: is-mod[7] |50> |no> sa: is-mod[7] |96889010407> |yes> sa: is-mod[3] |category 1: category 2: category 3: 286725> |yes>And I guess we should note that they work independent of the category/data-type (as do the other simple arithmetic operators). Here the first one has data-type "number". Those in the middle have no data-type. And the last one has "category 1: category 2: category 3".

Now, on to FizzBuzz. Here are the exercise details:

-- task: -- For numbers 1 through 100, -- if the number is divisible by 3 print Fizz; -- if the number is divisible by 5 print Buzz; -- if the number is divisible by 3 and 5 (15) print FizzBuzz; -- else, print the number.Here are three alternate potential ways to do it, but the incomplete parser meant only the third version actually worked:

|context> => |context: Fizz Buzz exercise in BKO: v1> |list> => range(|1>,|100>) fizz-buzz-0 |*> #=> |_self> fizz-buzz-1 |*> #=> if(arithmetic(|_self>,|%>,|3>) == |0>,|Fizz>,|>) fizz-buzz-2 |*> #=> if(arithmetic(|_self>,|%>,|5>) == |0>,|Buzz>,|>) fizz-buzz-3 |*> #=> if(arithmetic(|_self>,|%>,|15>) == |0>,|FizzBuzz>,|>) map[fizz-buzz-0,fizz-buzz] "" |list> map[fizz-buzz-1,fizz-buzz] "" |list> map[fizz-buzz-2,fizz-buzz] "" |list> map[fizz-buzz-3,fizz-buzz] "" |list> |context> => |context: Fizz Buzz exercise in BKO: v2> |list> => range(|1>,|100>) is-zero |*> => |False> is-zero |0> => |True> fizz-buzz-0 |*> #=> |_self> -- current parser can't handle the nested () fizz-buzz-1 |*> #=> if(is-zero arithmetic(|_self>,|%>,|3>),|Fizz>,|>) fizz-buzz-2 |*> #=> if(is-zero arithmetic(|_self>,|%>,|5>),|Buzz>,|>) fizz-buzz-3 |*> #=> if(is-zero arithmetic(|_self>,|%>,|15>),|FizzBuzz>,|>) map[fizz-buzz-0,fizz-buzz] "" |list> map[fizz-buzz-1,fizz-buzz] "" |list> map[fizz-buzz-2,fizz-buzz] "" |list> map[fizz-buzz-3,fizz-buzz] "" |list> |context> => |context: Fizz Buzz exercise in BKO: v3> -- define our list |list> => range(|1>,|100>) -- define is-zero function is-zero |*> => |False> is-zero |0> => |True> -- define is-mod functions is-mod-3 |*> #=> is-zero arithmetic(|_self>,|%>,|3>) is-mod-5 |*> #=> is-zero arithmetic(|_self>,|%>,|5>) is-mod-15 |*> #=> is-zero arithmetic(|_self>,|%>,|15>) -- apply them map[is-mod-3] "" |list> map[is-mod-5] "" |list> map[is-mod-15] "" |list> -- define fizz-buzz functions fizz-buzz-0 |*> #=> |_self> fizz-buzz-1 |*> #=> if(is-mod-3 |_self>,|Fizz>,|>) fizz-buzz-2 |*> #=> if(is-mod-5 |_self>,|Buzz>,|>) fizz-buzz-3 |*> #=> if(is-mod-15 |_self>,|FizzBuzz>,|>) -- apply them map[fizz-buzz-0,fizz-buzz] "" |list> map[fizz-buzz-1,fizz-buzz] "" |list> map[fizz-buzz-2,fizz-buzz] "" |list> map[fizz-buzz-3,fizz-buzz] "" |list>Now we have is-mod[k] we can give a nice pretty and tidy version:

|context> => |context: Fizz Buzz exercise, is-mod version> the |list> => range(|1>,|100>) fizz-buzz-0 |*> #=> |_self> fizz-buzz-1 |*> #=> if(is-mod[3] |_self>,|Fizz>,|>) fizz-buzz-2 |*> #=> if(is-mod[5] |_self>,|Buzz>,|>) fizz-buzz-3 |*> #=> if(is-mod[15] |_self>,|FizzBuzz>,|>) |null> => map[fizz-buzz-0,fizz-buzz] the |list> |null> => map[fizz-buzz-1,fizz-buzz] the |list> |null> => map[fizz-buzz-2,fizz-buzz] the |list> |null> => map[fizz-buzz-3,fizz-buzz] the |list>And here is the result:
