SAS Macro Interview Questions And Answers
To gauge your knowledge of the field, interviewers may ask you a variety of technical and nontechnical SAS macro interview questions. The following are some examples you can consider:
What is the difference between %STR and %NRSTR?
To make sure you are familiar with them thoroughly, your interviewer may inquire about various functions or the distinctions between various sets of functions. In your answer, you can define each function. You can then go into more detail about their main distinctions after that.
Example: ‘The %NRSTR and %STR functions are macro quoting functions. They display special tokens and other operators as constant text while concealing their true meaning. These two functions differ primarily in one respect: %STR cannot mask macro triggers, whereas %NRSTR can.
What are the basic elements of SAS macro?
Knowing the various parts of macro is crucial because it has numerous uses in SAS. You can list the fundamental components of a SAS macro in your response.
Example: The macro name, body, and parameters are the three main components of a SAS macro definition. The macro is invoked by the macro name, and the parameters may then be passed to the macro. When calling the SAS macro function, the system runs the macro’s body code.
To reduce the size of the code, SAS technology uses a term known as SAS Macro. It offers a simple means of transmitting information from one process to another. For dynamic programs in SAS, Macro is used. It contains variable and programs. Using the tool, we can run a macro that we’ve added to our code. Macros make our daily work easy and fast. Candidates should have knowledge on its functionality. There are number of positions available across all the locations.

These difficult SAS interview questions for beginners will help you better prepare if you are just starting out in this field and are getting ready for an upcoming interview.
The %macro statement is used to define a macro. A macro is a collection of SAS statements that can be executed in a single step and are stored collectively. The name of the macro and a list of parameters come after the %macro statement. The macro definition is ended with a %mend statement.
There are several ways that data sets can be used to store named lists of macro variables. The first method involves using a data set to store the values of macro variables that you wish to be able to use in various SAS programs. The second method involves using a data set to keep track of the values of macro variables that you want to be able to use in a single SAS program.
In SAS, there are a few different approaches to creating a macro. The most popular method is to start the macro definition by using the%macro statement. The%mend statement will then be used to finish the definition. The%include statement can be used to include a file that contains the macro definition as an additional method of creating macros.
A macro definition can contain comments in two different ways. the%* comment statement, which will comment out everything from the%* to the following semicolon, is the first option. Using the%nrstr function, which will comment out everything from the%nrstr(to the next%nrstr), is the alternative method.
A macro can be passed parameters in a few different ways. Utilizing the%macro statement, which defines the macro and the parameters it will require, is the most popular method. The%mend statement can also be used to end a macro definition. The%let statement, which will give macro variables values, is another way to pass parameters to a macro.
FAQ
How do macros work in SAS?
With the aid of macros, you can create a section of code once and use it repeatedly in the same or even different programs. By using macros, you can create data-driven programs that let SAS make decisions based on actual data values.
Why macros are used in SAS?
We can avoid writing repetitive code by using SAS’s powerful macro feature instead, which we can then use repeatedly as necessary. Additionally, it aids in the development of dynamic variables within the code that can accept various values for various executions of the same code.
How do I resolve a macro in SAS?
You can use these references anywhere in a SAS program. If a literal string contains a reference to a macro variable, double-quote the string to resolve the reference. Single-quotation mark-enclosed macro variable references are not resolved
What is a macro call in SAS?
Macros are compiled programs that can be called from a SAS command prompt or in a submitted SAS program. Like macro variables, you generally use macros to generate text. However, macros offer additional functions: You can control when and how text is generated by including programming statements in macros.
