Parameters
   
- pxdoc
 
       Resource identifier of the paradox database.
      
- num
 
       The record number is an artificial number counting records in the order
       as they are stored in the database. The first record has number 0.
      
 
  
   This function deletes a record from the database. It does not free
   the space in the database file but just marks it as deleted. Inserting
   a new record afterwards will reuse the space.
  
Note: 
    This function is only available if pxlib >= 0.6.0 is used.
