Hi,
New to tcl.
My system is linux and when I run from a terminal "echo $?" it returns
0 or 1 depending on the last command result.
Under tclsh when I run "exec echo $?" it returns "$?" where I expected
to see 0 or 1 !
what am I doing wrong?
thank you for your help

if you are exec'ing a command and need to know the return value
you get that directly with exec (and catch) - see man page for exec
