Below are some important SAS interview questions which are asked in most MNC company interviews for beginners or professionals.
6. What is the difference between SAS functions and procedures?
Functions expect values to be supplied across an observation.
Procedures expect one variable value per observation.
7. Which SAS Statement does not perform automatic conversions in comparisons?
The “where” statement does not perform automatic conversions in comparisons.
8. SAS contains how many data types? What are they?
SAS has 2 data types, Character and Numeric.
9. What is SAS GRAPH?
SAS/GRAPH software creates and delivers accurate, high-impact visuals that enable decision makers to gain a quick understanding of critical business issues.
10. Why is a STOP statement needed for the point=option on a SET statement?
When you use the POINT= option, you must include a STOP statement to stop DATA step processing, programming logic that checks for an invalid value of the POINT= variable, or Both. Because POINT= reads only those observations that are specified in the DO statement, SAS cannot read an end-of-file indicator as it would if the file were being read sequentially. Because reading an end-of-file indicator ends a DATA step automatically, failure to substitute another means of ending the DATA step when you use POINT= can cause the DATA step to go into a continuous loop.
