There's always one of my favourite ways...

set text [list]
lappend text "First Line"
lappend text "Second Line"
puts [join $text \n]

It leaves the text [foreach]able until the very last moment.  You just
have to remember that initial [set], or something similar (unless
you're certain the variable doesn't exist at all, and don't mind it
being a PITA to read).
