Re: [Jbeta] syntax for functions and modulo
Explicit definitions like fizzy require you to refer to the arguments explicitly. The right argument is assigned to y locally within the verb (right argument is assigned to x) fizzy =: 3 : 0 if. div35 y do. 'FizzBuzz' elseif. div3 y do. 'Fizz' elseif. div5 y do.

Re: [Jbeta] syntax for functions and modulo
Sorry just noticed that this is in the beta forum. Questions like this would be better asked and answered in the programming forum.

Re: [Jbeta] transfers
This is because of a dependency of 'math/misc/simplex' is 'numeric' math/misc/simplex contains: require 'math/misc/matutil' which contains: require 'math/misc/mathutil' which contains: require 'numeric' i.e. the numeric.ijs script is required. On J7 this script resides at: 'general/misc/numeric' On Wed, Jun 20, 2012 at 1:20 PM, Brian Schott schott.br...@gmail.com wrote: load'~addons/math/misc/simplex.ijs' not found: /j/addons/general/misc/numeric.ijs |file name error: script | 0!:0 y[4!:55'y' Good news and bad, again. The files in moth1misc one in their designated directory, but it looks like the `require 'math/misc/matutil'` in simplex.ijs requires a slightly different layout of directories. Where did 'general/' come from in the path? --- (B=) -- For information about J forums see http://www.jsoftware.com/forums.htm -- For information about J forums see http://www.jsoftware.com/forums.htm
