17# I have a problem with gawk 3.0.3 on linux with libc 5.4.33.
18# The memory is corrupted, if I use OFMT = "%.12g".
19# With OFMT = "%.6g" evrything works fine, but I don't have enough
20# digits for the computation.
21#
22# Thanks a lot,
23# Florian La Roche

25# Here is the sample awk-Script together with sample data:
26#
27BEGIN {
28		OFMT = "%.12g"
29		big = 99999999999
30		lowest = big
31		small = 0
32		highest = small
33		dir = ""
34	}
35$0 ~ /^[0-9]+$/ {
36	# some old awks do not think $0 is numeric, so use $1
37	if ($1 < lowest)
38		lowest = $1
39	if ($1 > highest)
40		highest = $1
41	next
42}
43$0 ~ /\/\.:$/ {
44	if (dir != "") {
45		if (highest != small)
46			print dir, highest, lowest
47		else
48			print dir, "-", "-"
49	}
50	dir = substr($0, 1, length($0)-3)	# trim off /.:
51	lowest = big
52	highest = small
53}
