Hi forum,

I'm fighting with a function like this! :)


function(["x","y","x"]) do |a,b|c|
 printf("%10s %10s %10s\n",a,b,c)
end


It works fine, but I would like a "pseudo-code" like this :)


new array

function(["x","y","z"]) do |a,b|c|
 push a,b,c into array
end

if array is not empty
 printf("%10s %10s %10s\n",a,b,c)
end


Which is the best way to write it?

Thank you very very much,
Al
