1. Introduction to SAS®

2. Objectives List the components of a SAS program.
Open an existing SAS program and run it.

3. SAS Programs
A SAS program is a sequence of steps that the user submits for execution.
Raw Data
DATA steps are typically used to create SAS data sets.
SAS Data Set
DATA Step
PROC Step
Report
SAS Data Set
PROC steps are typically used to process SAS data sets (that is, generate reports and graphs, edit data, and sort data).

4. SAS Programs DATA Step PROC Steps DATA one;
INPUT Name $ Gender $ Runtime Age Weight ;
DATALINES;
Donna F
Gracie F
Luanne F
Mimi F
Chris M ;
RUN;
PROC PRINT DATA=one;
PROC REG DATA=one;
MODEL Runtime=Weight;
DATA Step
PROC Steps

5. SAS Windowing Environment
Interactive windows enable you to interface with SAS.

6. Exercises Open the SAS program “example.sas.”
Submit the program and examine the results.

7. Objectives Learn the two fundamental SAS syntax programming rules.
Create a SAS dataset from a space delimited inline text file.
Create a SAS dataset from a comma delimited inline text file.
Create a SAS dataset from a comma delimited external text file.
Reading an Excel file PROC IMPORT via Import Wizard

8. Fundamental SAS Syntax Rules
SAS statements have these characteristics:
usually begin with an identifying keyword
always end with a semicolon
data staff;
input LastName $ FirstName $
JobTitle $ Salary;
datalines;
…insert text data here…
run;
proc print data=staff;

9. Example of a typical space delimited text file ‘space.txt’
Name Gender Runtime Age Weight
Donna F
Gracie F
Luanne F
Mimi F
Chris M

10. Creating a SAS data set from a space delimited text file: The Data Step
DATA one;
INPUT Name $ Gender $ Runtime Age Weight;
DATALINES;
Donna F
Gracie F
Luanne F
Mimi F
Chris M ;
RUN;
PROC PRINT DATA=one;

11. Example of a typical comma delimited text data set. ‘Comma.txt’
Name,Gender,Runtime,Age,Weight
Donna,F,8.17,42,68.15
Gracie,F,8.63,38,81.87
Luanne,F,8.65,43,85.84
Mimi,F,8.92,50,70.87
Chris,M,8.95,49,81.42

12. Creating a SAS data set from a comma delimited text file: The Data Step
DATA two;
INFILE DATALINES DLM=',' DSD MISSOVER;
INPUT Name $ Gender $ Runtime Age Weight;
DATALINES;
Donna,F,8.17,42,68.15
Gracie,F,8.63,38,81.87
Luanne,F,8.65,,85.84
Mimi,F,8.92,50
Chris,M,8.95,49,81.42 ;
RUN;
PROC PRINT DATA=two;

13. INFILE Options Option Description DLM=
INFILE "raw-data-file" <DLM=> <DSD> <MISSOVER>;
Option
Description
DLM=
Specifies an alternate delimiter.
DSD
Sets the default delimiter to a comma,
treats consecutive delimiters as missing values, and allows embedded delimiters when the data value is enclosed in quotation marks.
MISSOVER
Sets variables to missing if the end of the record is reached before finding values for all fields.

14. Creating a SAS data set from an external comma delimited text file: The Data Step
DATA three;
INFILE 'C:\USERS\BACONR\DESKTOP\comma.txt'
DLM=',' DSD MISSOVER FIRSTOBS=2;
INPUT Name $ Gender $ Runtime Age Weight;
RUN;
PROC PRINT DATA=three;

15. Example of a typical comma delimited text data set. ‘Comma.txt’
Name,Gender,Runtime,Age,Weight
Donna,F,8.17,42,68.15
Gracie,F,8.63,38,81.87
Luanne,F,8.65,43,85.84
Mimi,F,8.92,50,70.87
Chris,M,8.95,49,81.42

16. Reading an Excel File Typical Excel file: ‘myexcel.xlsx’

17. Creating a SAS data set from an EXCEL file:
PROC IMPORT via the SAS IMPORT WIZARD
32-bit SAS
64-bit SAS

18. Capturing the Syntax:
PROC IMPORT via the SAS IMPORT WIZARD

19. Creating a SAS data set from an EXCEL FILE: PROC IMPORT via the IMPORT WIZARD
32-bit
PROC IMPORT OUT= WORK.four
DATAFILE= "C:\Users\baconr\Downloads\myexcel.xlsx"
DBMS=EXCEL REPLACE;
RANGE="comma$";
GETNAMES=YES;
MIXED=NO;
SCANTEXT=YES;
USEDATE=YES;
SCANTIME=YES;
RUN;
PROC PRINT DATA=four;
