# Index Mark [:index mark]

Index Mark commands are used to report the progress of the text as it is spoken. Index marks are position markers; they do not modify heuristics or word pronunciations in any way. The index mark sequence inserts a flag into the text stream. When DECtalk Software encounters an Index Mark command, a message is sent to the calling application . Index marks cannot be put in the middle of a word. This command is synchronous. If a callback function or window procedure is not specified in the startup function, index marks in the text are ignored.
