exec output problem

[notmeatleast]

Hi guys,
Suppose a.tcl contains
puts "Hi"

and b.tcl contains
exec tclsh a.tcl

Now, when I run tclsh b.tcl, it just retruns to the % prompt without giving any output. Why's that? How can I achive that. I don't want to use source command, as I'll have a different interpreter than the one I'm running in.

Thanks in advance.

because exec "create" another process. and the stdout (for the puts) is in this new process.
because it is quite fast it dies instantly and you do not see anything.

try this in your b.tcl

source a.tcl

a try to avoid exec as much as you can.
if you need to run several task recompile Tcl/Tk to make it thread safe.
and then use the Tclthread extension.

Or if you are on unix use fork() anmd tclX.
