![]() What are the most common programming errors committed in SAS?Īnswer: Most commonly committed programming errors in SAS are: Do SAS ‘informats’ have any other functions?Īnswer: Apart from telling SAS on how to read data into variables, ‘informats’ input data from external files known as Flat Files ASCII.ġ4. Quite frankly, all you need to do to achieve this is to input the DESCENDING command into your code (or, rather, swap it with the ASCENDING command).ġ3. How to change sorting from ‘ascending’ to ‘descending’?Īnswer: As can you might’ve noticed there are a lot of comparisons in SAS interview questions. In such a situation, it can be tricky to draw a clear distinction – that’s why extensive studying beforehand is so important!ġ2. Some of these questions can be tricky – not necessarily because they’re difficult in of themselves, but because the two objects that you’re comparing might be very similar. It is more than likely that you’ll get quite a few comparison questions during your job interview. They only require one single variable to be able to perform the before mentioned observation. This is not the case with procedures, however. What’s the difference between a ‘function’ and a ‘procedure’?Īnswer: This might be one of the more tricky SAS interview questions to pinpoint – it’s quite easy to get mixed up between the two.Ī function in SAS requires specific argument values to successfully perform an observation. ![]() These sets are comprised of data and what is known as data dictionaries – lists that hold various information about the data within them.ġ1. The two types are called Character data and Numeric data.Īnswer: The “Data Step” is responsible for the creation of datasets. How many types of data are there in SAS?Īnswer: You could say that this is one of the easier SAS interview questions – there are only two data types in SAS. There are honestly quite a few functions that SAS performs – however, these are some of the main ones.ĩ. Name a few functions that SAS is capable of performing.Īnswer: Data management and storage app development improvement of quality. Whereas If want to process certain variables and do not want them to appear in the new data set, then specify drop = data set option in the data statement.Ĩ. What is the difference between using drop = data set option in data statement and set statement?Īnswer: If you don’t want to process certain variables and you do not want them to appear in the new data set, then specify drop = data set option in the set statement.
