From the example below in Lab: A Taste of J (2), I guess that adverbs are executed in a right to left order, even though J is typically read from left to right:
── (7 of 18) Adverbs (ctd) ────────────────────────────────── We can combine two adverbs. The following applies the +/ addition table with the same argument on left and right: ) +/~ 0 1 2 3 0 1 2 3 1 2 3 4 2 3 4 5 3 4 5 6 ... +/~ 0 1 2 3 NB Start of program 0 1 2 3 +/ 0 1 2 3 NB. ~
