Yes it does. Basically the first thing you run is in the
global namespace, `set myglobalvar 79' therefore sets a global
variable. However, when you run the same script from tclwebtest,
it's tclwebtest which is running in the global namespace, and your
script is being run in another namespace because it is being run
inside an `eval'.

Maybe tclwebtest could be modified to run inside a custom namespace
and then run the script with an `upvar' instead. Til, what do
you think?

Anyway, the solution to your problem is easy, before `set myglobalvar
79' put another `global myglobalvar' and it will work as expected:

   $ ./tclwebtest test 
   
   ----- START: test at [18/ago/2003:10:57:59] -----
   The value of the local variable is 4
   The value of the global variable is 79
   ----- SUCCESS: test (took 0s)               -----
