in reply to sub will not return data correctly (the way i want it to!!)

When you call your second subroutine, it's going to start through the first loop of your for(), do the four reads, then return. It's never going to do the other 3 loops.

If you want to do the loop four times and then return a list of all the results, you can do that. Create an array before your for() loop starts, then replace your return with a push to that array:

push @results, $foo1, $foo2, $foo3, $foo4;

Then after the for() loop is finished, return @results.
