Good tip once code fixed. Description says it returns 0/1 (for true/false), but code is -1/0. Also should the nor found be WARNING or ERROR? See Tips:Using NOTE, WARNING, ERROR in Your Program's Generated Messages. --Don Henderson 02:02, 17 January 2011 (UTC)
Sorry. Misread it. Does return 0/1. --Don Henderson 02:03, 17 January 2011 (UTC)
