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

I'm sure there are easier ways (awaits others to gleefully provide simpler solutions) but here's my offering:

a!localVariables(
  local!items: { "A", "B", "C", "D", "E", "F" },
  local!splitAttribute: fn!reduce(fn!split, ri!attributeName, local!items),
  a!forEach(
    items: local!splitAttribute,
    expression: if(
      fv!isFirst,
      fn!proper(fv!item),
      fn!concat(
        ri!attributeName[fn!find(fv!item, ri!attributeName, 1) - 1],
        fv!item
      )
    )
  )
)

The idea is to have the full set of characters that you want to use as delimiters in the string you want to process (I've only provide A-F as an example).

You then split the incoming string based upon that list. Unfortunately (j this instance) the split function excludes the value you're splitting, so you up wiht a list where the first item is whole but the remaining items are missing their first character. 

The aim of the remainder of the code is to re-append the missing character to each item in the list generated by the split processing.

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)))
      )
    )
  )
)
