Hey and welcome to this same lectures on dyslexia.

00:04.020 --> 00:13.630
You will learn how to use variables in its uses so valuable is if you don't know it from other languages

00:13.670 --> 00:21.720
is basically just the ability to store some information in a variable and then we use it as many times

00:21.780 --> 00:30.100
as you wish so you can for some will have a variable called X equals twenty pixels and then you will

00:30.510 --> 00:38.280
be able to use this variable x return to pay of as many times as you wish.

00:38.280 --> 00:46.290
And that's how you can use variables in SAS to improve your work because you will not have to type in

00:46.290 --> 00:50.850
the same code all the time you will just use it instead.

00:53.580 --> 00:58.380
So we are going to have a variable file and then we're going to have egg components thrown up inside

00:58.380 --> 01:03.210
that there's gonna be a type puppet goofy and that is successful.

01:03.300 --> 01:07.440
So we are going to have first of all different size of 20 pixel and

01:12.290 --> 01:15.350
then we're gonna have em from size.

01:15.350 --> 01:21.750
That is a slight one which we're also gonna use in the scores and then that's going to be of them.

01:21.830 --> 01:27.500
Twenty eight pieces and then we are going to use them inside

01:30.020 --> 01:35.600
our Tabak typography class a little bit later we are first going to structure to hate you more so in

01:35.600 --> 01:42.410
the hate mail we are going to have free paragraphs one for the font size normal 1 and in one for fun

01:42.410 --> 01:46.910
size is so large and then one for the extra extra large font size

02:21.460 --> 02:28.600
so we're just going to plan the classes as we usually would do like almost this and that's gonna be

02:28.600 --> 02:33.560
nothing different about this we're just gonna create tree classes where we're used to variables in the

02:33.570 --> 02:36.560
name and then it would be transformed into a successful

02:53.000 --> 02:59.970
so in science the component Shona we are going to have to typography and incited to pack a free class

02:59.970 --> 03:07.800
we're gonna have a variable now a class sorry with the class of font size

03:10.620 --> 03:18.660
large and inside font size Slattery are gonna then use to variable in depth and as you can see we can

03:18.660 --> 03:25.770
then say font size and thin because if I am done F for the verbal and then we can say font size which

03:25.770 --> 03:30.900
is the default one it's an S A large font size for having now and we can use this twenty five times

03:30.900 --> 03:37.110
if we wanted to adjust one time depending on how much we use it in your code and then we can go in and

03:37.110 --> 03:45.600
say font size is so large and font size so large and put it in the correct rebels for this one so then

03:45.600 --> 03:52.020
when you're transplanted m the transponder would know that this is twenty pixels so it will just be

03:52.020 --> 03:59.940
converted into trend to pixels and the reason why variables is important in SPSS is because it would

03:59.940 --> 04:12.000
allow you to have a more we use the same code the same amount of times and that gives you this widening

04:12.000 --> 04:18.600
so you can just change the font size for every single element that has this font size to trend to pieces

04:18.600 --> 04:21.750
instead of going into every single file and change it from their

04:29.060 --> 04:32.480
thank you very much for watching this nature see to next one.
