Running another exe program from Main Perl program without interupting

Friends,

I would like to run another (.exe) program from my perl main program
without any interrupting my main program.

Right now I am using

system("newprogram.exe");

But for this my main program is waiting for the new program to get
closed. I still want my main program to continue while the
"newprogram.exe"; is running.

Thanks

Joshy

In other words, you want to fork off a child process.

perldoc -f fork
perldoc perlfork

system( 1, "newprogram.exe");

perldoc perlport

As an optimization, may not call the command shell specified in
$ENV{PERL5SHELL}. system(1, args) spawns an external process and
immediately returns its process designator, without waiting for it to
terminate. Return value may be used subsequently in wait or waitpid.
Failure to spawn() a subprocess is indicated by setting $? to "255 <<
8". $? is set in a way compatible with Unix (i.e. the exitstatus of
the subprocess is obtained by "$? >> 8", as described in the
documentation). (Win32)

If you need more control have a look at Win32::Process.
