# Under SCO OpenServer 5.0.6a using gawk 3.1.0 compiled with gcc 2.95.2, this
# program:

    BEGIN {
	f1(Procs,b)
	print "test"
    }

    function f1(Procs,a) {
	# a[""]
	a[""] = "a"	# ADR: Give it a value so can trace it
	f2()
    }

    function f2() {
	# b[""]
	b[""] = "b"	# ADR: Give it a value so can trace it
    }

    # ADR: 1/28/2003: Added this:
    BEGIN { for (i in b) printf("b[\"%s\"] = \"%s\"\n", i, b[i]) }
    # END ADR added.

# gives:
