Perl Question - Assynchronousness

[James McDonald]

I have a perl script which scavenges file off a network share and then 
formats and feeds them in an ERP system.

What I would like to do is at the moment I feed the file into the ERP I 
would like to run another perl script which will wait for 10 seconds and 
then check to see that the ERP has spat the correct information out.

However I want the calling script to continue processing after it calles 
the called script.

I have been looking at system() but am unsure of how to tell it to 
launch the script and just keep going without waiting for a reply.

Any ideas?
