Assuming the data is dynamic and needs to be written to the file on occasion, that way is a lot harder. You either have to dedicate a namespace to it, or have a list of all the variable names that you want to write out. Also, you have to be careful of the content. Instead of only being sensitive to newlines, now you have to watch for unbalanced quotes/braces and of course evaluation brackets.

actually the easier way would to be to make the file in direct tcl source.

ie

set var1 "blah"
set var2 "bleh"

then just read it in with source
you may wanna enclose the source command from inside a catch command though incase the datafile is corrupt.

Probably the easiest way is to make the file like this:

varname1
data1
varname2
data2
varname3
data3
...

To read it:
set fp [open data.txt r]
set pairs [split [read $fp] n]
close $fp
array set data $pairs

Now you can access the data by saying $data(varname)

To write the data to the file:
set pairs [array get data]
set fp [open data.txt w]
puts -nonewline $fp [join $pairs n]
close $fp

Just make sure your data doesn't have linebreaks in it.
