This is elementary Tcl. I recommend reading a good tutorial on this.  
Anyway, you can use the 'global' command:

proc myProc {} {
    global id

   # ...
}

As a sidenote and depending on the project, I'd be careful about  
using a name such as 'id' in the global namespace as that could  
easily conflict.
