I know I know but it was in the wrong forum what are and how do they work along with... my instructer uses this to make a lower case = capital you know enter y for yes(y=Y have the same value) but he does some crazy stuff to do it. and this is not explained in my book...

delete the other thread if you want it in here...

i think you can toupper() the input and then do your conditional check. that way regardless of what they enter y or Y it will be Y or something else. kk?

or tolower(variable name)
