## cmp Combinator Take two values and three quoted programs on the stack and run one of the three depending on the results of comparing the two values. a b [G] [E] [L] cmp ------------------------- a > b G a b [G] [E] [L] cmp ------------------------- a = b E a b [G] [E] [L] cmp ------------------------- a < b L ### Discussion This is useful sometimes, and you can [dup] or [dupd] with two quoted programs to handle the cases when you just want to deal with [<=] or [>=] and not all three possibilities, e.g.: [G] [EL] dup cmp [GE] [L] dupd cmp Or even: [GL] [E] over cmp ### Crosslinks TODO: link to tree notebooks where this was used.
