Hello all,

To my mind, comfort with indexing is one of the differentiating factors for 
array programming vs. functional programming; J has grade as a primitive on par 
with sort.  

NuVoc lists /:@/: (rank) and permutation inversion as two uses.

Are there any examples you like that show off grade or perhaps indexing ({)?

Cheers,
Vanessa McHale
