# SAS Coding From Basic To Advanced
BY - Aniket Suresh Marwade

Remember --
- ROWS are called Observations.
- Columns are called Variables.
- In SAS each line of code ends with semicolon.
- SAS is insensitive to case (means you can write anyway like Data, data, dAtA all will give same result).
- SAS is insensitive to indentation (means in simple words it is not like python :smiling_face_with_smiling_eyes_and_hand_covering_mouth: )
-------------------

**Example 1:** Creating a Dataset.

Data Test; /*Dataset or Table*/
	a=1; /*Variable or Columns and their value*/
	Run;

---------------
**Example 2:** Create a data set that contains 3 variables.

Data Number;
	Var1 = 123;
	Var2 = 356;
	Var3 = 923;
	Run;

**Output:**

#### Creating Character Variables

Unlike other programming languages such as R, Java or C++, there are only two types of variable in SAS:

* Numeric
* Character

Creating a character variable is easy. You simply need to enclose them with a quotation mark.

Either single quotation ('John') or double quotation ("John") works.

**Example 3:** Create a dataset where you have character and numeric variables.

Data Food;
	Restraunt = "Burger King";
	Num_of_Employee = 5;
	Location = "Mumbai";
	Run;

**Output :**

-------

#### Creating Multiple Observations(Rows).

The majority of the SAS data sets contain multiple observations (Rows).


In order to create a data set that contains more than one observation, you need the Input and Datalines statements.

#### Input and Datalines Statement
Here in the below code,
* *Input* - lists variables(columns) to be created.
* *Datalines* - it signals SAS to begin reading the data on the next line.

**Example:** Create a dataset with 3 obervation.

Data Test1;
	Input a b c;
	Datalines;
	1 3 4
	2 7 9
	12 45 56
	;
	Run;

**Output:**

#### Creating multiple obervations(Rows) for character using Input and Datalines.
