I agree true tolower/oupper is locale dependent. But I only use tolower/toupper for Latin alphabets so that I do not need api for case conversion. However tolower/toupper is used in J standard library and it may cause error in some cases. eg, in find dialog box if ijs contains text above code point 256 like ĀāĂ㥹ĆćĈĉĊċČčĎďĐđĒēĔĕĖėĘęĚěĜĝ case-insensitive search for any string such as 'abc' will raise an index error: tolower -- regards, bill ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
