This is driving me barmy...can any kind soul here explain why this works:

on tryLoopWith
  put "a,b,c,d,e,f" into charList
  repeat with n = 1 to the number of items in charList
    put item n of charList into line n of newCharList
  end repeat
  put newCharList && "with"
end tryLoopWith
but this throws up a 'bad chunk expression" :

on tryLoopFor
  put "a,b,c,d,e,f" into charList
  repeat for each item n in charList
    put item n of charList into line n of newCharList
  end repeat
  put newCharList && "for"
end tryLoopFor
In your second example, the variable n doesn't contain a number but 
the actual value of the current item in the list.

Try this:

on tryLoopFor
  put "a,b,c,d,e,f" into charList
  repeat for each item n in charList
    put n & return after newCharList
  end repeat
  delete char -1 of newCharList ## delete final return
  put newCharList && "for"
end tryLoopFor
