Libraries

Permanent library

We can create permanent library by following steps –

First click on leftmost button under Libraries .

It will open following window of New Library –

We give name satya to new library . We click on checkbox to re-create library every time when we open SAS Studio.  

We click on Browse  , then it will open this window –

Then , click on OK button to create library .

We can see SATYA library under My Libraries tab  as –

We can also create permanent library by using libname statement in SAS 9.2 window version.

libname satya “C:\Users\dell\Desktop”;

We create a new dataset apple and store in satya library.

Data satya.apple;

You can see library SATYA store APPLE dataset .

We do not store anything in our dataset . So , it shows this window –

Temporary library

We create a dataset to store it temporarily as –

Data abc;

/*OR*/

Data work.abc;

The dataset stores in Work library . As you can see ABC dataset under Work library in below window –

Data step

The structure of Data step  is as-

Data dataset_name;

Input variable_names;

Datalines/Cards;

Data             <-    We enter data to store in dataset

;               <-     It shows end of data

Run;

Data  – It is used to create a dataset with dataset_name as name of the dataset .

Input – It shows the list of variable names.

Datalines/Cards – It is used to read data internally. We used Cards in previous version of SAS.

Data – it shows the data to store in the dataset.

Run  – To execute the program .

SAS variable types

It has two types –

Numeric variable

This is the default variable type . It store only digits from 0 to 9 .

Syntax –

 INPUT VAR1 VAR2 VAR3;

We create three variables VAR1 , VAR2 , VAR3 .

We can create id ,salary  and age variables as –

Input id salary age ;

Character Variable

It store data which includes string, digits and special symbols like marine , abc12 , #dfg89 etc.

Syntax –

INPUT VAR1 $ VAR2 $ ;

We create two character variables VAR1 , VAR2.

We create character variables name , gender as –

Input name $ gender $;

We create a new dataset “new” . It stores name and marks of students .SAS reads line-by-line to store data in dataset .It reads data column-wise separated by space.  

Data new;

input name$ marks;

datalines;

Satya 45

Ram 78

;

run;

We can execute our SAS code by using F3 function key .

It shows output of program in OUTPUT DATA window –

We create a dataset “abc” . It includes id , name and salary .

data abc;

input id name$ salary ;

datalines;

101 Dan 45000

102 Derry 8564

103 Henry 87562

;

run;

We can execute our SAS code by using F3 function key .

The output of SAS code can be seen in OUTPUT DATA window –

The dataset ABC store in WORK library .
