Hello,

Is system 1, supposed to return the child's pid? It seems to return -1 when I tested it out. Is there any other windows command that might return the child's pid?

Thanks for the response.

I believe it should. Have you tried printing `"$!"` and/or `"$^E"`? They may give you a meaning the cause of the error.	[reply] [d/l] [select]

The "piped open" (See perlopentut) returns the pid of the child process. See also Re^5: question about running a system and a perl function background in this thread for an example of use.
