*--------------- begin example ---------------
local x "a b c"

// make sure there is only one space between elements
local x : list retokenize x

// replace "space" by "_1 space"
local y : subinstr local x " " "_1 ", all

// add _1 for the final element
local y "`y'_1"

// see the result
di "`y'"
*---------------- end example ----------------
