cnt - index counter
cnt N ..
Cnt counts from 0 to N-1, producing N lines of output. If multiple
arguments are given, cnt produces a nested array of values where the
final counter rotates fastest through its range. Cnt is most useful in
conjunction with rcalc(1) to produce array values.
To create a 3 by 5 array:
cnt 3 5
