want to convert "indiaChinaFrance" to "India China France"

Could not hold me back. My looping function solution.I am sure Mike will love it ;-)

a!localVariables(
  local!input: "indiaChinaFrance",
  proper(
    reduce(
      substitute(_, _, _),
      local!input,
      merge(
        char(65+enumerate(26)),
        apply(concat(" ", _), char(65+enumerate(26)))
      )
    )
  )
)

Stefaaaaaan   I am not mike, but  I remember during our last call I mentioned the factor of maintainability regarding coding :D
perhaps that is the most elegant way of all the above, but absolutly hell for people who shall maintain that.  "reduce" in combination of merge and on top (multiple) "_" is definitly not inituive to read....

It is a beautiful piece of code though!  Not sure I even knew the proper() function existed until now..

Might as well include my solution here also

a!localVariables(
  local!input: "indiaChinaFrance",
  joinarray(
    a!forEach(
      items: enumerate(len(local!input)),
      expression: a!localVariables(
        local!char: charat(local!input,fv!index),
        if(
          fv!isFirst,
          upper(local!char),
          if(
            code(local!char)<97,
            concat(" ",local!char),
            local!char
          )
        )
      )
    )
  )
)
