There is no real need to use file "foobar" (unless you want it). This
will also work, and save some complexity:

	BEGIN {
	       outcmd = "tr '[a-z]' '[A-Z]'"
	      }
	      {
	       print $1 | outcmd
	      }

If you wanted "foobar", you could tack " | tee foobar" on the end
of outcmd. To get even simpler, you could get rid of outcmd
completely with

	{ print $1 | "tr '[a-z]' '[A-Z]'" }
