How to use the exec command correctly

[programmer28]

Hello,

I would like to run this dos command from TCL: "udplisten 7777 > test.txt" which is sitting in this local address c:/Program files/myProgram/udplisten.exe.

The problem is that when I am using the exec command I receive an error "No such file or directory"How do I do that correctly???

Try using 'file nativename'.

if {[file exists [file nativename $str]]} {
    exec [file nativename $str]
}

Don't know what your udp listener does, but tcl
has an easy to use UDP add-on.
