Strange String Glitch #2

We're glad you came by, but you might find what you're looking for elsewhere. TI-Basic Developer is not the site it once was. While its information on commands and other calculator features remains almost second-to-none, its forum, archives, and even hosting service, Wikidot, have been decaying for years. The calculator community would love to see what you're working on, or help you in your next coding adventure, but TI-Basic Developer is no longer the place to do it. Instead, you should head over to Cemetech (primarily American) or TI-Planet (primarily international). Both are active, well-established forums with their own archives, chatrooms, reference material, and abundant coding tools and resources. We'll see you there, we hope.

Strange String Glitch #2

Ok, so a week or so ago, I made a program that would prompt a string, using the Input command, and then put it into a message for the user to see:

PROGRAM:HMMYES
ClrHome
Input "WORD:",Str1
ClrHome
"Hmm, yes, the "+Str1+"here is made out of "+Str1+"."-->Str2
Output(1,1,Str2

I figured out that any string I inputted into the program, even if it had double quotes (") in the middle, would show up in the final result.
For example, if I put in just " for Str1, it would output:

Hmm, yes, the " here is made out of ".

I did some experimentation and figured out that this worked with any program, and changed what the Input command was followed by, and found that as long as you are prompting a string with the Input command, you can put double quotes into it.
This could mean a whole world of new things that could happen with strings containing double quotes, and although there are still some [obvious] limitations, we now know that Input, and (to an extent) Disp and Output( are able to do this. I hope what I found will benefit the TI-BASIC community.

I don’t think this is a glitch; Its long been established that TI-Basic doesn’t function like most other languages, and a lot of that is due to its strict typing and tokenization of commands. The quotes inside of a string are not tokenized, and so are rendered as literal text, as opposed to being considered a program token and ending a string. It may be unique behavior, but in many languages there is an escape chatacter for putting quotation marks into a string.

Oh, thanks, I didn't know that. I guess I got excited. But in any case, it's still kind of cool.
