I get the same problem if I substitute "00E0" with "00E1" to # "00E9". Other strings don't have have this problem (for example, "00EA"). # The problem occurs whether I use file input or whether I manually assign # "$0" (as above). # # The problem is also discussed in a comp.lang.awk posting ("Bug in GAWK # 3.1.1?", Dec. 27, 2002). # # -Serge
