What are the best practices for SAS comments?

Re: Commenting standards I find that it is best to put brief comments before sections of code. This could be a single proc or data steps, but will also frequently be a little less often. For example if you have two proc sorts followed by a merge then that whole block only needs one comment.

How to run SAS code faster?

Use only the variables that you need. DROP and KEEP statements and DROP= and KEEP= SAS data set options will instruct SAS about which variables you need. Using DROP= and KEEP= on the input data sets is more efficient than using them as program statements because they don't bring the unneeded variables into the buffer.

How do you optimize performance in SAS?

To improve the performance of a SAS job, you must reduce the number of times SAS accesses disk or tape devices. To do this, you can modify your SAS programs to process only the necessary variables and observations by: using WHERE processing. using DROP and KEEP statements.

How to improve SAS code performance?

1) Use KEEP= or DROP= data set options to retain desired variables. 2) Use WHERE statements, WHERE= data set option, or WHERE clauses to subset SAS datasets. 3) Create and access SAS datasets rather than ASCII or EBCDIC raw data files.

What are the best practices for SAS code comments?

Every SAS program should start with a main block of comments, emphasized by asterisks. The block of comments should include the filename, by whom the program is written, the date on which the program was written, and text that clearly describes the main purpose, input, and output of the program.

How can I make my code more efficient?

Here are some steps you can take to improve the efficiency of your code: Create function. Repetitive processes can be a real drag in software development. Use loops strategically. Avoid unnecessary variables. Leverage object-oriented programming. Focus on horizontal scalability. Leverage cache. Aim for statelessness.

How to improve SAS programming skills?

Overall, the best way to improve your SAS programming skills is to practice regularly, seek out opportunities to learn from others, and stay up to date with the latest developments in the field.

How to make SAS code more efficient?

Use only the variables that you need. DROP and KEEP statements and DROP= and KEEP= SAS data set options will instruct SAS about which variables you need. Using DROP= and KEEP= on the input data sets is more efficient than using them as program statements because they don't bring the unneeded variables into the buffer.
