Managing *.dbf tables II?

Hi guys,
I hope someone could help me with this.

I have a c.dbf table. This is a temporary table. Data gets posted to it all the time during the application works. Now, I need to create another database table ? ?d.dbf?. This one would not be a temporary, but the final table in the application. The c.dbf collects rows (records) during the day. The rows get appended in it as the user posts them (row by row). Now I need to create this d.dbf table. On a menu-click (at the end of the day) all data from c.dbf should be posted to d.dbf. But d.dbf should have 2 extra fields for each row, first a field where a True/False sign could be posted (which would say if or not data has been sent to some communication device) and a second field that would be a counter ? will generate a unique ascending number. So, at this menu-click event c.dbf should be emptied and all it?s data appended to d.dbf. Plus, d.dbf should get the True/False sign in it?s first extra field from the communication device (data sent or not sent). Can someone help me to write all this in code?

If this writing is not clear enough, please do tell me which part of the question should I rephrase.

Thanks, Blash

Thanks ntony for your code. It seems good. I haven't time to implement it right now, at work they've changed my priorities. But we'll be in touch.
