Igor and Werner: Thank you so much for your replies to my post! Igor, I hate to be such a noob but when you reply "Fail 3 times." Do you mean fail to make an acceptable entry three times so that I will finally give in and enter a long and tedious "acceptable" entry in order to go on? Also you submitted a code example. Is this a patch that will allow a lesser entry? If so how do I use it? I'm willing but not much of a modern programmer.
My time as a commercial programmer was spent in the 80s as a Prime Information Database programmer/administrator. Prime Information ran on a Prime minicomputer that took up a good sized room. The 300mb disk had 14" platters. Primos OS>PrimeInformation>InfoBASIC/SQL was the cutting edge at the time. My hobby machine back then was an old 4K Atari 800 with a cassette tape storage. I upgraded to 24K memory and a dual disk 88k floppy drive.
Werner you are right about "a confirmation and warning" question should be sufficient. My Commercial programmer son gifted me the Raspberry Pi that I play on now learning python. I am working on a numerology program while I learn.
