Looking at http://perldoc.perl.org/functions/system.html and the docs on my own installation I find no reference to putting a 1 as the first parameter of a system call. I am using it like this: 
system(1, $progname);

So that I do not have to wait for hte external programme to return.

Where is this documented?
