| Thanks Christian, that works... the issue with building up a nested
string dynamically is that the newlines are being lost in calls to
concat. For example:
% set newline "\n"
% set test "teststring {"
teststring {
% set test [concat $test$newline " channel {"]
teststring { channel {
....I don't want to lose the newlines - at this point, I want $test to
contain:
teststring {
channel {
....so, in mucking around some more it is becoming clear to me that the
call I wish to make is "append" rather than "concat", as in:
% set newline "\n"
% set test "teststring {"
teststring {
% append test [append newline " channel {"]
teststring {
channel {
....brick-by-brick - Tcl syntax is a mind-warp. I'm sure I'll love it
with some more practice.

[append] puts strings together. [concat] puts *lists* together. Since
you appear to want to work with a string, newlines and all, you don't
want [concat].
But the string you're building appears to be treated as a list at some
point, so I'm not sure why you would care about the newlines as opposed
to some other whitespace.
