Something like fun {Join L C} case L of H|nil then H [] H|T then H#C#{Join T C} end end {Join MyArray ", "} Would probably do it. Also, I believe ruby/python/php have array functions which do these things; php uses implode, which is quite useful. ^^ Use a functional language, 1 function takes list, has two cases… it’s like 3 lines of code. Something like

fun {Join L C}

end

{Join MyArray “, “}

Would probably do it. Also, I believe ruby/python/php have array functions which do these things; php uses implode, which is quite useful. ^^
