how to get my tcl exec to run in background on windows 2000

[Nancy McDaniel]

I am trying to get my tcl exec to run in the background.  I can re-direct the output and stderr (ex. 2>&1) but this shouldn’t cause the actual process to right in the background correct??

I saw something in my researching indicating that I can put it after the last arg on my exec but my called exec says I have passed it too many args.  

I am doing the following

if { [catch {exec $callprog $arg1 $arg2} resulterr] } {

   puts “unsuccessful call $resulterr”

}

else { puts “successful call” }

I have tried re-directing stdout/stderr.  Any ideas on how to get it to run in the background?

thanks,

Nancy
