Petit Computer - 1 PRINT and INPUT

Video tutorial.

PRINT and INPUT

The QR code if you want it

Hello! I'm CKlidify, and in this tutorial I will teach you how to use the PRINT and INPUT commands!

PRINTEdit

When using the PRINT command, you must make it look something like this

PRINT ""

Now, inside of those quotation marks you can write ANYTHING that you want! Such as:

PRINT "I love CKlidify!"

Now, if we get out of edit mode and type RUN into the console, you should see something like this:

PetitComputer ver2.2
SMILEBASIC 1048576 bytes free
(C)2011-2012 SmileBoom Co.Ltd.

READY
RUN
I love CKlidify!
OK

Now you can ignore the

PetitComputer ver2.2
SMILEBASIC 1048576 bytes free
(C)2011-2012 SmileBoom Co.Ltd. 
XLLLTESTTUT

QR Code for 3DS/DSi XL/LL users

in the console everytime! It's just talking about copyright, SMILEBASIC, how many bytes free, blah blah blah!


INPUTEdit

When using the INPUT command, you must make it look something like this

INPUT "";VAR$

Now, what this does. Is prints whatever you type in the quotation marks, then wants you to input something. Once you have given an input. Your input will be saved under the name "VAR". You can change VAR to anything, but keep the dollar sign! Now, if you leave it as is but add text to the quotes

INPUT "What's on your mind";VAR$

then exit edit mode, type run in the console and answer it, it will look like this:

READY
RUN
What's on your mind?
You
OK

Notice how we didn't add the question mark to the INPUT, but it showed up in the console? That's because, all INPUTS are questions originaly! So it automatically adds a question mark! But now, let's say you want their input to be a NUMBER! If so, you would change your code to this:

INPUT "What's on your mind";VAR

By removing that dollar sign it automatically knows you want the input to be a number. So let's change the words

INPUT "Can I have a number";VAR

Now, let's load up the console and type RUN and answer it:

READY
RUN
Can I have a number?
2
OK

But, if you type something that's not a number, you'll see this:

READY
RUN
Can I have a number?
NO
?Redo from start
Can I have a number?

So it will keep asking you input a number, until you ACTUALLY input a number!

PRINT + INPUTEdit

Now let's combine our brand new skills to create a half decent program! If we continue from where we left off with the INPUT, but change the input back to words and change the question

INPUT "What is your name";VAR$

Then add a PRINT command under it

INPUT "What is your name';VAR$
PRINT VAR$

Now, what this will do is, once you input your name, it will print it back to you. Let's exit edit mode and type RUN in the console to see what it looks like:

READY
RUN
What is your name?
Carson
Carson
OK

Now, what we can do is make it so once you input your name, it will print "Hello Carson" (With Carson being the person's name) Now, when doing this, do not try dong it like this:

INPUT "What is your name";VAR$
PRINT "Hello VAR$"

Because that would actually print "Hello VAR$" and we want it to print their name! So that would be achieved like this:

INPUT "What is your name";VAR$
PRINT "Hello " + VAR$

Now, what this does it add their name after "Hello "! Now, why are we putting a space after "Hello"? Well, if we don't add that space it would print like this "HelloCarson". So the space will basically add a space between the two words. Now let's exit edit mode, and type RUN in the console!

READY
RUN
What is your name?
Carson
Hello Carson
OK

And there you have it. You can get this program through the QR Code provided with this post! In the QR Code there is additional code, such as COLOR and BEEP commands. I will go over those in the next Tutorial!

On to the next tutorial!
