This recipe shows one technique for building up a local macro with
pieces in " ":

local foo
local f1 just waking up
local f2 stretch and groan
local f3 stuff
local f4 breakfast

forval j = 1/4 {
    local foo `" `foo' "`f`j''" "'
}

mac li

_foo:            "just waking up" "stretch and groan" "stuff" "breakfast"
_f4:            breakfast
_f3:            stuff
_f2:            stretch and groan
_f1:            just waking up
