Viktor, your result does not match Raul's and only the first verb in fns seems 
to be being executed:

   fns eachdyad
(-~ +/)"1&.>/"_1@:(<@[ ,. ])

Am I missing something?

Nice line Raul.

The tacit adverb eachd based on your code is:

  eachd=:@.0(&.>)/("_1)(@:(<@[,.]))
  (<rnge) fns eachd data
+--------------+--------------+--------------+--------------+
| 2  1  0 _1 _2| 0 _1 _2 _3 _4| 5  4  3  2  1| 2  1  0 _1 _2|
|11 10  9  8  7| 4  3  2  1  0|21 20 19 18 17|11 10  9  8  7|
|20 19 18 17 16| 8  7  6  5  4|37 36 35 34 33|20 19 18 17 16|
|29 28 27 26 25|12 11 10  9  8|53 52 51 50 49|29 28 27 26 25|
|38 37 36 35 34|16 15 14 13 12|69 68 67 66 65|38 37 36 35 34|
+--------------+--------------+--------------+--------------+

If it is important that the left argument of the verb stay unboxed,
the following tacit adverb eachdyad should be helpful:

  eachdyad=:@.0(&.>)/("_1)(@:(<@[,.]))
  rnge fns eachdyad data
+--------------+--------------+--------------+--------------+
| 2  1  0 _1 _2| 0 _1 _2 _3 _4| 5  4  3  2  1| 2  1  0 _1 _2|
|11 10  9  8  7| 4  3  2  1  0|21 20 19 18 17|11 10  9  8  7|
|20 19 18 17 16| 8  7  6  5  4|37 36 35 34 33|20 19 18 17 16|
|29 28 27 26 25|12 11 10  9  8|53 52 51 50 49|29 28 27 26 25|
|38 37 36 35 34|16 15 14 13 12|69 68 67 66 65|38 37 36 35 34|
