I don't know the intricacies of the Windows version of Tcl's exec.

Is it possible that %20 gets munged because the shell thinks it's supposed 
to be an argument expansion? I recall that in COMMAND.COM %20 meant like 
what $20 means in /bin/sh... Does the % sign have to be doubled in order 
to make it a literal percentsign for COMMAND.COM ?
