Also, since symbol names are normally unique, if the arguments are symbols with the same name, they are ＠code{eq}. For other types (e.g., ＠＠ -2264,7 +2266,7 ＠＠ the same name are not ＠code{eq}. ＠xref{ the same name are not ＠code{eq}. ＠xref{Creating Symbols}.) NOTE: Under XEmacs 19, characters are really just integers, and thus -characters and integers with the same numeric are ＠code{eq}. Under +characters and integers with the same numeric code are ＠code{eq}. Under XEmacs 20, it was necessary to preserve remnants of this in function such as ＠code{old-eq} in order to maintain byte-code compatibility. Byte code compiled under any Emacs 19 will automatically have calls to _______________________________________________ XEmacs-Patches mailing list XEmacs-Patches(a)xemacs.org http://calypso.tux.org/cgi-bin/mailman/listinfo/xemacs-patches
