A dyadic function is one that takes an argument on the left and right of the function. Here is an example of a dyadic function named deal to deal hands of cards:
∇ k ← count deal cards;C
[1] c ← count
[2] k ←''
[3] Q:
[4] k ← k, cards ? 52
[5] c ← c-1
[6] →(c>0)/Q
[7] k←count cards ⍴ k
∇
So an execution of this function to deal 6 hands of 7 cards could produce the following:
6 deal 7
28 1 8 24 32 47 27
38 46 1 43 3 40 7
47 28 26 7 39 2 37
36 12 48 46 47 31 13
24 52 13 25 20 30 47
23 25 43 21 15 52 14
Some system functions are dyadic,
