How can I have non-case sensitive input?

[asdfasdf123]

What is it you are trying to achieve?
I'm trying to make a survey program to prepare for my compsci final exam.


What is the problem you are having?
The program requires non-case sensitive input, which I have no clue how to program.


Describe what you have tried to solve this problem
I've tried editing the if statements to have more options (see code below) and looking up answers


Post any relevant code (You may choose to attach the file instead of posting the code if it is too long)

Turing:

var hand, topHand1, topHandTotal : string var income, topIncome, totalRightIncome, totalLeftIncome, totalIncome, prevIncome, num, leftNum, rightNum : int var rightAvg, leftAvg, avgIncome : real totalRightIncome := 0 totalLeftIncome := 0 totalIncome := 0 num := 0 leftNum := 0 rightNum := 0 put " " : 25, "Welcome to the Income Survey" put "" loop     num := num + 1     put "Are you left handed or right handed? " ..     get hand     if hand = "right" or hand = "Right" then         put "You are right handed."     elsif hand = "left" or hand = "Left" then         put "You are left handed."     end if     exit when hand = "done"     put "Please enter your income: $" ..     get income     totalIncome := totalIncome + income     if hand = "right" then         totalRightIncome := totalRightIncome + income         rightNum := rightNum + 1     elsif hand = "left" then         totalLeftIncome := totalLeftIncome + income         leftNum := leftNum + 1     end if     put ""     if num = 2 then         if income > prevIncome then             topHand1 := hand             topIncome := income         elsif num > 2 then             if income > prevIncome and income > topIncome then                 topHand1 := hand                 topIncome := income             end if         end if     end if     prevIncome := income end loop leftAvg := totalLeftIncome / leftNum rightAvg := totalRightIncome / rightNum avgIncome := totalIncome / num if totalLeftIncome > totalRightIncome then     topHandTotal := "left" elsif totalRightIncome > totalLeftIncome then     topHandTotal := "right" end if put "" put "Summary for the given data" put "Average income of left handed people: $", leftAvg put "Average income of right handed people: $", rightAvg put "A ", topHand1, " handed person makes the most, earning $", topIncome put "On average, ", topHandTotal, " handed people earn more money" put "Thank you for using the Income Survey Program"

Please specify what version of Turing you are using
4.1 1.0.1

The easiest method is to convert all input to either lower or upper case before checking it. Loop over every character, and if it's the wrong case, change it to upper or lower. Then do your comparisons as normal.

also the commands for doing this are

Turing:

Str.Upper("string you want to convert")

for converting it all to upper case or

Turing:

Str.Lower("string you want to convert")

for converting it all to lower case.
