Problems with globals?

Hi, it's me again.  :-)

I was trying to develop a link-walk algorithm to validate that all the links
on a web-site
were valid and recursion combined with a list of already visited links
appeared to be the
way to implement it.  However, I can't seem to use globals within
tclwebtest.  Here's a
dumb TCL script which I found on a web site somewhere that illustrates
global variables:

#! /cygdrive/c/tcl/bin/tclsh.exe
proc dumb_proc {} {
    set myvar 4
    puts "The value of the local variable is $myvar"

    global myglobalvar
    puts "The value of the global variable is $myglobalvar"
}

set myglobalvar 79
dumb_proc

As expected, when run, it produces the following output:

$ ./global.tcl
The value of the local variable is 4
The value of the global variable is 79

However, if I try to run it using tclwebtest (without the "#!
/cygdrive/c/tcl/bin/tclsh.exe"
line, I get the following:

$ ../tclwebtest global.test

----- START: global.test at [30/Jul/2003:07:52:51] -----
The value of the local variable is 4

can't read "myglobalvar": no such variable
    while executing
"puts "The value of the global variable is $myglobalvar""
    (procedure "dumb_proc" line 6)
    invoked from within
"dumb_proc"
    (file "global.test" line 10)
    invoked from within
"source global.test"
    ("uplevel" body line 3)
    invoked from within
"uplevel $uplevel $to_eval "
in "global.test" line 10:
    puts "The value of the global variable is $myglobalvar"
}

set myglobalvar 79
dumb_proc

-----  FAILED: global.test (took 1s)               -----

DURATION: 1
1 of 1 tests FAILED:
global.test

Does tclwebtest do something that interferes with global variables?

Thanks,

Gordon Molek
