To reach this option, the user should select option 4 from the main menu. This option will allow the user to enter some documentation. It will also allow some changes to program functionality.

For the main booking screen, i.e. item 'EXAMPLE', the user should enter a Y for MULTI MODE. This will allow the user to ADD, AMEND and DELETE any bookings made. It will also allow an ENQUIRY on those bookings. In addition, this routine requires that the CONCAT character is set to '*'. All other entries can be left blank as they will take their default values although you may wish to incorporate the PRINT/DUMP function.

After entering the required fields, the screen will be as follows.
