Ok i have a program using a select case to convert letters to special charaters. My question is how can I get the code to read upper and lower case letters without having to put the upper case letters in my select case statement.

Example: Part of my code is

case "a"
word = "1"

and if i type apple i get 1pple

My question is, is there a way for me to type Apple and get 1pple without having to add this to my code

case "A"
word = "1"


I have been searching the commands char.toupper and char.isupper but i don't know how to implement them in my code. I know the code will word is i add the case "A" to my select case statement but I am trying to shorten up my code. I hope I am asking this question correctly.
