Hey, I have a bit of code I want to include into something large, but I'm hitting a wall.
({:`([:$:0 1&+)@.(9&<@{.)@(([:*/"."0@":@{.),{:))"1(|:@,:1:))50 25 33 22 293 1 2 1 1 3 Okay. Slap on some parens, and it fails? Valence error for {:..? Both resolve to 3, a verb, according to 4!:0. Because both verbs are monadic, I tried capping either and both, all composing conjunctions, parenthesizing. Adding in ]. or [., I don't see what the problem is, or how tail's valence fits into it? Some configurations increase the dimensions and don't give out the desired thing: (({:`([:$:0 1&+)@.(9&<@{.)@(([:*/"."0@":@{.),{:))"1 @ (|:@,:1:))50 25 33 22 293 1 0 0 0 1 1 0 0 1 0 0 0 1 0 0 0 1 1 1 0 However, assigning both to names and composing does work q=:|:@,:1: w=:({:`([:$:0 1&+)@.(9&<@{.)@(([:*/"."0@":@{.),{:))"1 w q 50 25 33 22 293 1 2 1 1 3 (w@q)50 25 33 22 293 1 2 1 1 3 What am I missing? This to me is unexpected behavior. I expect parethesization and variable substitution to be identical, but it's not. I'm sure there's a single, explanatory/exculpatory line somewhere about assignments, variables and or parentheses on the wiki, but it's not easily discoverable.. ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
