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. |

The & operator joins two strings together, one after the other, returning one large string.
:"Hello"&"World"
"HelloWorld"
:5→n
:"The value of n is "&string(n)
"The value of n is 5"Appending strings is very useful when you want to display text. If you want to display more than one string on the same line, for instance with the Text command, you'll need to use & to combine the strings.
By default, & doesn't put in any separation between the strings, which can look weird: you can see this in the above example, where joining "Hello" and "World" made "HelloWorld". With multiple uses of &, you can put in any separator you like:
:"Hello"&" "&"World"
"Hello World"If you want to use & to build up a string from scratch, start with "" — the empty string.
