This is a quick look at what is a table. How do you put data into a table. Using pairs to display the table. Then accessing an individual table element.
.@Brucewe An easier way to load a table is shown below.
kTab={"1","2","3","4","5","6","7","8","9","0","+","-","*","/","="}
That works, but in a later version the index values are not in numeric order. I am trying to keep things simple by having one way of doing things.
Thanks for the comment. I will accept all of the advice I can get.
that’s how we all learn! 
(actually, dave1707’s suggestion will work regardless of the order, you just list them in the order that you want them to be in).
