I'm creating a number of long documents which will be generated from Indesign Tagged Text files.
The documents will comprise of a series of linked text frames defined in the master and then auto-flowed.
Does anyone know if it's possible to automatically insert text at the start of each of the linked frames – ideally a variable?
Not directly in the text flow, unless they happen to fall in the right places. Why not make the linked frames shorter and add your variables in another frame above them?
Unfortunately it's not possible to know whether the text frame will need a title (it's basically to indicate that the text is continued from the previous frame), and space is at a premium!
Have you considered using a runing header?
