Re: Run-time expression eval in text fields



Adding separate field locations for each symbol unit requires a symbol
library file format change which is going to happen after v5 is
released.  Please do not change any of this code because it will just
get replaced when this occurs.

They could then add a text field to their units (marked shared-between-units or not as required), and set the value to something like “%REF” or “%VALUE”.  The expression evaluator could even be as simple as doing those two replacements, or maybe looking up any field value or something.
