Thismode should correspond to your computer platform and Intersystems software.DescriptionThe $ZUTIL(68,22) function specifies how Caché handles escape sequences when updatingthe $X special variable. When reading a string containing an escape sequence, various Inter-Systems products handle updating the $X special variable differently. You can control theway Caché updates $X when writing a string containing an escape sequence. Default behaviorsfor various implementations (including non-InterSystems ones) are:• UNIX parses the ANSI-standard escape sequence and counts the rest of the non-escapecharacters in the string against $X.• Alpha VMS does not count any more characters in the string against $X after encounteringan escape character ($CHAR(27)).• Open M [DSM] counts all characters in a string, including the escape character, against$X.• MSM counts all characters in the string, except for the escape character, against $X.To alter the system default setting for $X updating, see $ZUTIL(69,22) — $X Update Modefor Escape Sequences.Invoking $ZUTIL(68,22) without specifying n returns the current switch setting.610 Caché ObjectScript Reference
