Visual Logic and Design 8th Edition Chapter 7 Debug Program

Description

These solutions below just need to be built in Visual Logic.
Debug 01
// Each time a salesperson sells a car at the
// Pardeeville New and Used Auto Dealership,
// a record is created containing the salesperson’s
// name and the amount of the sale.
// Sales of new and used cars are kept in separate files
// because several reports are created for one type
// of sale or the other. However, management has requested
// a merged file so that all of a salesperson’s sales,
// whether the vehicle was new or used,
// are displayed together. The following code is intended
// to merge the files that have already been
// sorted by salesperson ID number.
