My thanks to Henric Cronström for taking the time to review my post on expression variables. He said the name for this new feature is still being decided. And he had some valuable information for getting started.

Your text is good and everything is correct. But you may want to add the following

1) The “all” qualifier is removed from the documentation and is replaced by “{1} total” which does exactly the same. “all” will still work in formulas in documents, though.

2) The syntax {$<Year=2002>} replaces the list of selected values with “2002″.

3) The syntax {$<Year+=2002>} adds “2002″ to the list of selected values.

4) The syntax {$<Year+=-2002>} removes “2002″ from the list of selected values.

5) The syntax {$<-Year+=2002-2001>} adds “2002″ and removes “2001″ to the list of excluded values. (Forced exclusion – see And-mode or red selection in attached app.)

Cheers
