    Thanks ! Can you post programs based on WHILE…WEND ,READ…DATA & RESTORE on site . Many pograms are not done in class and when it comes for exam then our sir claims that it has been covered in class and so we have to face a lot of problems . It will be very easy for us to get programs readymade .PLEASE !!!!!!!!!
