Is there a way to make quest distinguish between a capital letter and a lowercase? For example, I have an object...a computer....and when you examine it, you get a menu. One of the options is to log on, and if you choose it, you are prompted to type in a password....Which is entered into a string variable...Now, can I make it that, say the password is "Me," you have to type in "Me," with a capital "M," and not "me." I saw some kind of function that said $ucase()$ or something like that. I experimented, but to no avail. Is this even possible?

Unfortunately it's not possible to do this. Why do want case sensitivity anyway - won't it be annoying for players?

Not to mention the fact that players would assume the password wasn't case sensitive and so it wouldn't occur to them that "Me" and "me" were different things.
