Red_Dragon has asked for the wisdom of the Perl Monks concerning the following question:

All knowing Monks,

What must I code to start a Perl script from within a Perl script(if such a thing is possible) that will be totally independent of the launching script. This is to run on a Win2000Pro system running Perl 5.8. Thank you for any consideration.

    Win32::Process using the DETACHED_PROCESS flag should do what you want. 
    Win32::Process::Create($ProcessObj,
               "c:\\perl\\bin\\perl.exe",
               "perl script.pl",
               0,
               DETACHED_PROCESS,
               ".")|| die Win32::FormatMessage(Win32::GetLastError());

      The code snippet worked beautifully. Many thanks, your investment is not wasted.

    You want to detach a process from another. Look up forking, detaching, and parent-child relationships. Good luck!

    Here is some code I wrote years ago to do just that.
    This is working Win32 code.
    Look at sub Process_this_Device() for relevant code.
