Execute another program but don't wait.

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

Esteemed monks,

Aside fomr using a small batch file, is there a way of executing an external program and return wiothout waiting>

My code creates a ODF file, I want to launch Acrobat Reader to display the file, but I want my own app to continue without waiting for Acro Reader to close.

`fork`+`exec`: The unix system calls (but works in Windows due to a fancy hack). `Win32::Process`: The Windows system call. `system 1,`: May only work in Windows `IPC::Open2` and `IPC::Open3`: Standard modules that use the best way for the current OS, while allowing you to specify the child's STDIN, STDOUT and (in Open3's case) STDERR.

Either `system('command &');` or fork() and then exec().	[reply] [d/l]

On windows OS's 'command &' will not work but you can use 'start command' instead.	[reply]

That replaces the current process. If you want your program to continue, you should fork first.	[reply]
