Your answer really did, what I wanted.

Is it possible to return the output back into the calling script.

Like .. taking the above script as example i.e. 'x.pl' and its two values => $foo, $bar

Now I have another script lets call it 'y.pl'

Now from 'y.pl' I am calling 'x.pl' and simultaneously passing these values.

Then the output of 'x.pl' back to 'y.pl'. Something like 'return' does

Thanks For any help
