SAS Programming Language Cheatsheet

SAS (Statistical Analysis System) is a powerful and versatile programming language used for data analysis, statistical modeling, and business intelligence. Whether you’re a seasoned SAS programmer or just getting started, having a handy cheatsheet can be invaluable for speeding up your workflow and ensuring accuracy. In this blog post, we’ll provide you with the ultimate SAS Programming Language Cheatsheet – a quick reference guide to essential commands, functions, and syntax.

1. Basic SAS Syntax

DATA Step

DATA dataset_name;
   /* Your data processing code here */
RUN;

PROC Step:

PROC procedure_name DATA=dataset_name;
   /* Your procedure code here */
RUN;

Comments:

* This is a comment;

2. Data Manipulation:

Reading Data:

DATA dataset_name;
   INPUT variable1 variable2;
   DATALINES;
   value1 value2
   value3 value4
   ;
RUN;

Selecting Columns:

DATA new_dataset_name;
   SET old_dataset_name(KEEP=variable1 variable2);
RUN;

Filtering Rows:

DATA new_dataset_name;
   SET old_dataset_name;
   IF condition;
RUN;

3. Statistical Analysis

Descriptive Statistics:

PROC MEANS DATA=dataset_name;
   VAR variable_name;
RUN;

Correlation:

PROC CORR DATA=dataset_name;
   VAR variable1 variable2;
RUN;

Regression:

PROC REG DATA=dataset_name;
   MODEL dependent_variable = independent_variable1 independent_variable2;
RUN;

4. Output and Reporting:

Print Dataset:

PROC PRINT DATA=dataset_name;
RUN;

Exporting Data:

PROC EXPORT DATA=dataset_name
   OUTFILE='path/to/output/file.csv'
   DBMS=CSV REPLACE;
RUN;

5. Macros:

Defining Macros:

%MACRO macro_name(parameter1, parameter2);
   /* Your macro code here */
%MEND;

Calling Macros:

%macro_name(value1, value2);

6. Error Handling:

Log Messages:

OPTIONS MLOGIC MPRINT SYMBOLGEN;

Conditional Statements:

%IF condition %THEN %DO;
   /* Code to execute if condition is true */
%END;
