Predefined constants are true and false:
<lang scheme>
{if true then YES else NO}
-> YES
{if false then YES else NO}
-> NO
</lang>
Following the lambda calculus user defined booleans can be built
<lang scheme>
{def TRUE {lambda {:a :b} :a}}
-> TRUE
{def FALSE {lambda {:a :b} :b}}
-> FALSE
{def IF {lambda {:c :a :b} {:c :a :b}}}
-> IF
{IF TRUE yes no}
-> yes
{IF FALSE yes no}
-> no
</lang>
