PLS, I NEED TO BE GUIDED ON HOW TO WRITE A SIMPLE PROGRAM IN BASIC THAT WOULD PROMPT 3 LEVELS OF AUTHENTICATION WHEN UNAUTHORISED LOG-ON IS EFFECTED.
You are not going to be able here to get detailed help on the program code, as there are many, many versions of BASIC language.
What I would do, if you have not begun, is to write a logic pattern (flowchart) of what you want to do. Doing that will allow you to compartment the code writing to independent steps.
