Step 1: Learn patience. This is a forum of volunteers who typically have full time jobs. Or, are asleep, as I was at the time you posted this.

As for (1), your question is not clear. You said that the data for A and B comes from code. If that's the case, then how can the user modify it? Are you displaying the data on a front panel control? If so, just change it to an indicator. Problem solved.

As for (2), I don't understand this one either. You said that C is a calculated value, but then you say the user can change the date. What date?

Your statements are contradictory. Please be more clear in your problem statement.
