Transcript

- [Instructor] Transmitting to an output device involves transmitting, usually to a screen, and displaying items. We can use two functions, one being print, and I can print pretty much anything that I'd like. I can create and assign a variable, X, and I can choose to print this to the output device, being the screen. I could also, if I wanted to, I could view X, but that would bring up my date of viewer. So this is a different part of the interface available with our studio. Another function I might use instead of print is, if I had multiple pieces of strings that I wanted to put together, I could use CAT function, short for concatenate. I can do, any thing testing one two three, to mix up strings and integers. I could also have many strings connected via a comma. And as a final concluding thought, after having assigned a variable, instead of having assigned a variable, four, five, six, seven, eight, nine, to X, I could use, brackets, round brackets, outside of this expression to print this directly onto the screen at the same time as creating that variable.
