Is there a way to add a text by reference using LaTeX? I have several text references to 'versionXX.yy'. I wonder if I can define this in one place so I don't need to update it in all places.
Thanks
You could define a variable or new command with your version at the beginning and then just use this definition. See here
Btw. there is a special site called tex.stackexchange.com for this kind of questions.
