Stored Procedure For Archiving The Records In Another Table

I have two tables called A and B and C. Where A and C has the same schema

A contains the following columns and values
-------------------------------------------
TaskId   PoId   Podate         Approved

   1       2    2008-07-07      No
   3       4    2007-05-05      No
   5       5    2005-08-06      Yes
   2       6     2006-07-07     Yes


Table B contains the following columns and values
-------------------------------------------------
TaskId      TableName   Fromdate     Approved_Status

1                A        7/7/2007     No
3                B       2/4/2006      Yes

Now i need to create a stored procedure that should accept the values (Yes/No) from the Approved_Status column in Table B and should look for the same values in the Approved  column in Table A. If both values match then the corresponding rows in Table A should be archived in table C which has the same schema as that of Table A. That is the matching columns should get deleted from Table A and shoud be inserted into Table C. In both the tables A and B i have the TaskId as the common column

Pls provide me with full stored procedure code.
