xmessage and tcl


I need to do this in tcl ... In my program, I would like to have an xmessage pop up for user to select one of the buttons. And then based on the selection, I will perform different things:-

set msg1 "xmessage -center -print \" Testcase packaging for \" -buttons proceed,cancel"
if { [catch { eval exec $msg2 } results]} {
return $results

When I run it in tclsh, I can see the xmessage, and if I select the button "proceed", I got the following in my tclsh. How can I get rid of the "child process"?

% proceed
child process exited abnormally
