You can run a system command via:
`perl myPerlScript.pl`

or check the system method

Hi,

Thanks for the information, but how can I get the results from our perl
script.???

actually, we find out that we can use this code:

obj = IO.popen("/usr/bin/perl hello_world.pl world", "w+")
obj.close_write
toto = obj.gets
obj.close
puts toto

but is there other way to do this?

Well:

foo = `type readme.txt`

will put the contents of readme.txt into foo, so is good for grabbing
stdout from the external app

Or you can check out popen3 if you need separate acces to STDIN, STDOUT
and STDERR
