Re: ?? exec prog << value ??

Ok, I have a file called example.tcl

the file contains the following commands:

-----------------------------------------
set var 4+4\n

puts $var

set result [exec test_prog << $var]

puts $result
-----------------------------------------

The output is:
-----------------------------------------
4+4

syntax error
can't read "result": no such variable
-----------------------------------------
The message "syntax error" is created by
test_prog when there is no mathematical expression.

Thanks for your help,
Zeh Mau
