QBasic Tutorial 23 - Palindrome Program - QB64



This tutorial will show how find if a word or string is a palindrome. A palindrome is a word or string that is the same printed forwards and backward.

Examples of Palindrome 
bob
noon
1991
redder

Note
The Oxford English Dictionary states that the longest palindromic word is tattarrattat.

The Guinness Book of Records states that detartrated is the longest word and a soap dish vender saippuakuppinippukauppias is a long palindrome name. (Don’t ask me how to pronounce that name).

Note
The program uses LCASE$ instead of UCASE$. LCASE$ converts strings to lowercase.
